SAP Fiori deployment options and SAP Fiori front-end server strategy – UPDATE 2021

**This blog post is updated on March 2022 **

Update March 2022: Release of SAP Fiori front-end server 2021 for SAP S/4HANA SP01 which includes SAPUI5 1.96 as long-term maintenance version and outlook on SAP Fiori front-end server 2022 for SAP S/4HANA.

Update October 2021: Release of SAP Fiori front-end server 2021 for SAP S/4HANA and updated version of document SAP Fiori deployment options and system landscape recommendations. Alternative options for the UIBAS001 version when upgrading to SAP FES 2020 or SAP FES 2021.

Update May 2021: Additional hints regarding SAP Fiori front-end server maintenance period according to SAP note 2217489 and restrictions regarding the compatibility of apps of component UIBAS001 600 with S/4HANA backend releases, as described in SAP note 2436567.

————————————————————————————————————————————

This blog post delivers a short summary of the different SAP Fiori front-end server versions and the related deployment options. For more details, please check the document SAP Fiori deployment options and system landscape recommendations.

SAP Fiori front-end server 6.0 is a long-term, stable UI technology foundation for SAP Fiori apps of SAP Business Suite and SAP S/4HANA systems, see also blog post. The end of maintenance of SAP Fiori FES 6.0 (end of 2027/30) relates directly to the maintenance period of SAP Business Suite.

SAP Fiori front-end server 6.0 and the predecessor versions can be deployed embedded or as a standalone server/hub for SAP S/4HANA and SAP Business Suite systems. The embedded deployment for SAP S/4HANA systems is the recommended setup. The standalone server deployment for SAP S/4HANA systems is mainly used by customers due to security aspects for external access scenarios.

In addition, for SAP Business Suite systems, the SAP Fiori front-end server can serve as central hub to offer a single entry point to multiple systems. This is not possible for an SAP S/4HANA system landscape, because of the version dependencies of the SAP Fiori UI components and backend versions.

The SAP Fiori front-end server versions up to 6.0 support all SAP S/4HANA and SAP Business Suite releases, down to SAP NetWeaver 7.40 based installations. This enables customers to consume new UI technology innovations by a selective upgrade of the SAP Fiori front-end server without touching the backend components.

SAP Fiori front-end server 2020 for S/4HANA (FES 2020) was initially dedicated to the SAP S/4HANA product. Due to mandatory legal requirements related to accessibility, also SAP Business Suite apps are released for SAP Fiori front-end server 2020 as of SP01. This allows customers to reach accessibility compliance for SAP Business Suite apps by using the new SAP Fiori front-end server version as a central hub or standalone server.

SAP Fiori front-end server 2021 for S/4HANA (FES 2021) has the same deployment recommendations as the predecessor versions (embedded for SAP S/4HANA systems, hub deployment for Business Suite). FES 2021 does not support IE11 browser any more.

Stack Definition:
SAP FES 2020 contains the software components SAP_UI 7.55 (including SAPUI5 version 1.84 as long-term maintenance version) and UIBAS001 600.
SAP FES 2021 contains the software components SAP_UI 7.56 (including SAPUI5 1.96 as long-term maintenance version) and UIBAS001 700. SAP FES 2021 Sp01 was just released end of February 2022.
For more information on planned support packages please refer to Schedule for maintenance deliveries.

Supported Products:
SAP FES 2020 can be used for
the SAP S/4HANA releases: 1809, 1909 and 2020 and for SAP Business Suite systems. Lower SAP S/4HANA releases are not supported.
Please note, that there are restrictions regarding the compatibility of UIBAS001 600 apps/components with S/4HANA 1809/1909, see SAP note 2436567.
To resolve this, you can keep the UIBAS001 version to 500 while upgrading SAP_UI to 7.55 during an upgrade to FES 2020 in an SAP S/4HANA 1809 or 1909 installation. For more details, see SAP note 2217489.

SAP FES 2021 supports the newest S/4HANA releases: 1909, 2020 and 2021 and SAP Business Suite systems. There are restrictions regarding the compatibility of UIBAS001 700 apps/components with S/4HANA 1909/2020, see SAP note 2436567.
To resolve this, you can keep the UIBAS001 version to 500 or 600 while upgrading SAP_UI to 7.56 during an upgrade to FES 2021 according to the SAP S/4HANA release 1909 or 2020. For more details, see SAP note 2217489.

Deployment Options: For SAP S/4HANA systems both deployment options – embedded and standalone FES server – are supported. The embedded  deployment  is  the recommended one.
SAP Fiori front-end server cannot serve as central entry point (hub) to multiple S/4HANA systems, see SAP Fiori deployment options and system landscape recommendations.

For SAP Business Suite systems only the hub or standalone server deployment is supported – not the embedded deployment. This is due to the minimum SAP NetWeaver version 7.52.

Outlook – SAP Fiori front-end server 2022 for SAP S/4HANA

For October 2022 the release of a successor SAP Fiori front-end server product version is planned. It will contain SAP_UI 7.57 including SAPUI5 1.102 and UIBAS001 7.57. Still the same deployment options and recommendations as for SAP FES 2020/2021 are valid.

SAP Fiori front-end server with SAP S/4HANA – upgrade options

As shown in the graph, you can upgrade the front-end server components without upgrading the S/4HANA product version. This is valid for the embedded and for a standalone server deployment. To resolve some dependencies of UIBAS001 600/700 apps to the S/4HANA backend version (see also SAP note 2436567) you can keep the UIBAS001 version according to the fitting S/4HANA backend version while upgrading the SAP_UI component (including SAPUI5) to the newer version, see SAP note 2217489.

Technically SAP Fiori front-end server as of version 2020 and higher versions require SAP NetWeaver 7.52 as the minimum release. This is required to be able to consume technology features, such as OData Version 4.0, and thus reduces technical limitations for future UI technology innovations.

For lower SAP S/4HANA releases an upgrade to the long-term maintenance version SAP Fiori front-end server 6.0 is recommended. Please refer also to this blog post.

Please note that in general SAP Fiori front-end server versions have a two-years maintenance period. Then you need to upgrade the SAP Fiori front-end server components. SAP FES 6.0 as a long-term maintenance version is an exception. See also SAP note 2217489.

SAP Fiori front-end server with SAP Business Suite – upgrade options

SAP Fiori front-end server 2020/2021/2022 for SAP S/4HANA both support SAP Business Suite systems in a hub/standalone server deployment. The scenario with a central front-end server hub with one SAP S/4HANA system and one or several SAP Business Suite systems (the so-called “mixed” scenario) is still a possible deployment option.

Remark: In case you want to have IE11 support beyond the end of maintenance of FES 2020, which is end of 2023, you should stay with SAP FES 6.0.

Future Direction

SAP’s strategic direction is to evolve powerful alternatives for a SAP Fiori front-end server as a central hub or standalone server with a much lower TCO on customer-side.

The front-end server hub as central entry point to multiple systems with UX integration capabilities is covered by the SAP Launchpad Service on SAP Business Technology Platform, which will further evolve over times.

Currently alternatives for securing the backend systems without a SAP Fiori front-end server (e.g. in the DMZ network zone) for external access scenarios are being evaluated.

      Hi Carola,

      Thanks for detailed explanation here.

      In future upgrades with S/4HANA for example from S/4HANA 2020 to 2021, will front end server 2020 required to upgrade ? Or there will be just support package upgrade for FES components?

      Regards,

      Hi Rupesh,

      A new SAP S/4HANA release comes with a new SAP Fiori front-end server version as a minimum.  The new SAP Fiori front-end server components, you would get with the installation of SAP S/4HANA as embedded deployment. In case of a hub deployment you would need to upgrade the SAP Fiori front-end server accordingly. But so far there are no plans/details available on a future SAP Fiori front-end server version 2021.

      Kind regards

      Hi Carola,

       

      thank you for the update and the good overview.

      Is the FES 2020 a requirement for the CDM-Integration into the Cloud Lanchpad aka cFLP? Or will this be available for older FES releases as well?

       

      Best regards,

      Hi Timo,

      thanks for your question.

      The CDM content exposure feature is planned to be delivered also with SAP Fiori front-end server (FES) 6.0 as downport.

      In this case, the prerequisite for CDM integration into cFLP for SAP S/4HANA and Business Suite systems, is to upgrade the SAP Fiori front-end server components to SAP Fiori front-end server 6.0, which is the long-term maintenance release of SAP FES.

      Kind regards

      Hi Carola,

      can you confirm if this response is still valid? I tried to federate S/4 HANA content from an 1909 system to a Cloud Portal (CF) Launchpad, which did not work. I opened a ticket and was told that this feature would not be supported for 1909 (which runs with a 6.0 FES).

      Thanks and best regards

      Dear Carola,

      Thank you for the update. I also like especially the Pros and Cons for HUB architecture section in the Recommendations Document.

      Two Questions:

      • You describe the HUB scenario as “One single place to serve central functionality like Inbox, search, notification, etc.” Are there also plans for OnPrem customers who cannot switch to the Cloud and can’t use the central SAP Fiori launchpad?
      • FES 6 means SAPUI5 control set shipped with 1.71. Are there plans for control down port in SAPUI5? Living seven years with the current state are a long time for Business Suite and SolMan.

      Thanks,

      Stephan

      Hello Stephan,

      Thanks for your feedback.

      Currently it's not planned to offer a central entry point on-premise with the desired UX integration capabilities besides the central Fiori launchpad on SAP Cloud Platform.

      You could setup a dedicated front-end server where you can deploy central apps like My Inbox and  custom apps or define custom Fiori launchpad content to access apps of a dedicated system or link to system-specific Fiori launchpads. But it's not a real central entry point with deeper integration of apps running on different systems.

      In general there are no plans to downport new controls to lower SAPUI5 releases. New UI innovations for on-premise systems are expected to be delivered mainly with the new SAP S/4HANA releases.

      Kind regards

      Carola

      Dear Carola, thanks for this insight into SAP plan's related to the Fiori FES.

      Am I understanding it right, that customers who will be using the new FES 2020 as a hub, will not be able to connect this new FES 2020 to a S/4 HANA backend (e.g. 1909) and at the same time to a business suite backend (e.g. SAP ECC 6.0) ?

      Consequenlty this would mean, that the hub deployment for FES 2020 does only make sense from security perspective (external access etc.) as you have mentioned previously. Any other scenarios (mixed-scenario) are not relevant/possible anymore.

      Thanks for clarification.

      Hi Wladimir,

      exactly. The mixed scenario with a FES hub for an SAP S/4HANA and a business suite backend is no more supported with FES 2020.

      Hi Carol,

      In your Blog you write

      SAP Fiori front-end server 2020/2021 for SAP S/4HANA both support SAP Business Suite systems in a hub/standalone server deployment. The scenario with a central front-end server hub with one SAP S/4HANA system and one or several SAP Business Suite systems (the so-called “mixed” scenario) is still a possible deployment option.

      So whats the status in end of 2021?

      There is really no note which gives a clear answer.

      Even not Note 2217489 - Maintenance and Update Strategy for SAP Fiori Front-End Server

      UIBAS001 500 for Business Suite and <= S4H 2019
      UIBAS001 600 for S4H 2020

      or is 600 downward compatible and can be used for BusinessSuite as well?

      Kind Regards

      Hi Reto,

      SAP Fiori front-end server 2021 still supports SAP Business Suite.

      The UIBAS001 600 dependencies apply only for SAP S/4HANA applications.

      Kind regards.

      Does it really mean when using sap Business Suite ERP as backend and integrated FES 6.0, there will be no upgard-possibilty. So we have to switch so s/4 hana otherwise UI 1.71.xx is the last release we could ever use? This is not soo cool *g*

      Hello Oliver,

      Yes, new UI technology innovations for on-premise systems will come with SAP S/4HANA only. But FES6.0 will be supported until end of maintenance of SAP Business Suite. So, there is no need to upgrade, because the EOM of the FES version as before.

      If you want to use new features delivered with SAP Fiori Front-end server 2020. e.g. for custom developed apps, you could deploy them on a separate FES.

      Kind regards.

      Hello Carola,

      just to be clear. FES 6.0 will be the last FES available for ECC 6.0 systems. so UI 1.71.xx will be the last version useable as long as we stay on FES integrated in an ECC 6.0 system, is this correct?

      no good news, but anyway, we are in upgarding to s/4 hana within the next year 😉

      Hi Mathew,

      the Quartz Dark theme comes with SAPUI5 1.72 and therefore it's currently not included in SAP Fiori front-end server 6.0. But we are evaluating a downport of the dark theme to 1.71.

      Hi

      We are planning to migrate from Hub to embedded and plan to run both deployments concurrently until we are sure that the hub is working fine.

      We, however, have one S/4HANA system which will be the embedded system. Is it possible to have this system act as the Frontend server (Embedded) and at the same time be the backend system for the existing Hub FES?

       

      Thank you

      Hi Timothy,

      The embedded deployment inludes that the Fiori UIs are deployed on the same system.

      From the Hub you can link to the FLP or single apps of this embedded system or also can get data from it of course.

      Kind regards

      Hi Carola Steinmaier

      Have a query here, we plan to connect the new s/4 hana 2020 FES(hub setup) to s/4 hana 2020 backend. Client also has CRM, SRM - Suite on Hana systems. So will we be able to connect to these systems via s/4 hana FES 2020 under the cetral hub architecture ? or have to do an embedded setup for the SOH systems.

      Hi,

      the FES 2020 as hub cannot be used to deploy SoH apps on the same. SAP Fiori front-end server only supports S/4HANA 2020/1909/1809 systems, as described in the Blog post.

      For the SoH apps, the SAP FES 6.0 is the most recent and long-term maintenance version, which can be used in an embedded or standalone server hub) deployment.

      Kind regards,

      Hi Carola Steinmaier

      Today I  read about the new FES 2020  and the option to use it on S/4 HANA 1909 systems:
      2769531 – SAP S/4HANA 1909: Release Information Note, 
      2919182 – SAP Fiori front-end server 2020 for SAP S/4HANA

      When updating a S/4HANA 1909 Initial Stack -> S/4HANA 1909 FP03, is it advisable to upgrade  from FES 6.0  to  FES 2020  in an embedded S4/HANA szenario or would you recommend to do this only when upgrading to S/4 HANA 2020:
      Looks like there are 2 options:

      • SAP Fiori Frontend Server 2020 (SAP User Interface Technology 7.55, SAPUI5 1.78.xx) = SAP FIORI FES 2020 FOR S/4HANA [ SPS Initial Shipment]
        SAP FIORI FOR SAP S/4HANA 1909 [ SPS 03 (11/2020)
        SAP S/4HANA 1909 [ SPS 03 (11/2020) ]
      • SAP Fiori Frontend Server 6.0
        SAP FIORI FOR SAP S/4HANA 1909 [ SPS 03 (11/2020)
        SAP S/4HANA 1909 [ SPS 03 (11/2020) ]

      Which one is recommended? Upgrade of our S4/HANA system to S/4 HANA 2020 is probably planned  2022 or later. FES 6.0 has longterm support. FE 2020 might have some new features but is brandnew.

      BTW: note 2775163 – SAP-Fiori-Frontend-Server 6.0 – General Information – SAP ONE Support Launchpad  should be corrected, as actually there is still written:
      SAP S/4HANA 1909 is only supported for SAP Fiori front-end server 6.0
      I opened a customer message and hope this will be corrected

      Hi Uta,

      Thanks for your comment. In general, I would recommend to use the newest version of SAP Fiori front-end server, that means SAP Fiori front-end server 2020. Features, as e.g. Pages/Spaces in SAP Fiori launchpad are only avaialble with this newest Fiori UI technology stack.

      For productive usage, we recommend to use the maintenance version (SAPUI5 1.84), which will be released with SAP Fiori front-end server 2020 Sp01 in February 2021.

      Of course you can do the general upgrade right now to FES 2020 Sp00, but then you would need to upgrade to FES2020 Sp01 soon. Just to be aware.

      The FES notes are always dedicated to a certain version (e.g. 5.0 or 6.0) and reflect was is available at that point in time of the release of this version. This was handled like this also for the previous FES notes. But, I get your point and will check, how we could avoid misunderstanding.

      Thanks and kind regards.

      Hi Stephan,

      this is due to accessibility requirements as mentioned in the blog:

      "Due to mandatory legal requirements related to accessibility, SAP will also release SAP Business Suite apps for SAP Fiori front-end server 2020 as of SP01. This allows customers to reach accessibility compliance for SAP Business Suite apps by using the new SAP Fiori front-end server version as a central hub or standalone server".

      Is it planed to offer support for Business Suite for the next FES releases?

      Or is it not recommended to upgrad to FES2020 if we need support for the FES till 2027 for a Business Suite system?

      Dear Carola,
      is there an update to this statement now that FES 2021 is released?

      When looking into https://launchpad.support.sap.com/#/notes/2977715/E/diff (Version 9) one would see that support for most "business suite apps" (read product versions) came in February.

      Currently FES 2021 does not support e.g. "FIORI ERP APPLICATIONS X1 1.0" when looking into the similar https://launchpad.support.sap.com/#/notes/3069754

      So basically: Will there be a "part two" where the same product versions will get support for FES 2021 as there is in FES 2020  or is the current list in 3069754 final

      Many thanks and kind regards

      Dear Carola,

      we discuss internally to upgrade an embedded FES on a S/4 HANA system or not. Because of that we notice that the EOM of the FES is not the same as the EOM of the S/4 HANA system.

       

      For Example:

      S/4 HANA 2020  EOM  31.12.2025

      SAP FIORI FES 2020 FOR S/4HANA  EOM 31.12.2023

      Is the FES2020 supported till the EOM of the s/4 hana system (31.12.2025)? Or, is it necessary that we update only the FES on the S/4 HANA 2020 system to (for example) FES2022 for support reasons?

       

      Thanks and Regards

      Hello Christian,

      SAP Fiori front-end server 2020 currently has a planned end of maintenance until 31.12.2023. These are two years - similiar to the previous FES versions (except FES 6.0).

      After these two years you need to upgrade the SAP Fiori front-end server version to get further support, yes.

      Thanks and kind regards.

      Hello Carola,

      that means we must update the embedded FES in the S/4 HANA 2020 for support? And the embedded FES is not supported similar to the S/4 HANA system till 2025.

      Thanks and Regards

      Hi Christian,

      Yes, you need to update the FES components (UI technology) to a newer version after EOM of FES 2020.

      This is the standard behavior since years.

      Hi Carola,

      We currently have SAP S/4HANA 1709 with embedded Fiori in our landscape and we are planning a technical upgrade targeting SAP S/4HANA 2020. As understood by reading this blog and couple of SAP Notes, I cannot directly upgrade to S/4HANA 2020 as 1-step approach, rather I will have to opt for 2-step approach -

      SAP S/4HANA 1709 (FES 4.0) -> SAP S/4HANA 1709 (FES6.0) -> SAP S/4HANA 2020

      Please correct me if you find me wrong with my understanding.

      Do I have to perform these jumps manually or SAP SUM tool does the job in single run?

      Please share your thoughts.

       

      Thanks and Regards,

      Hi Hitesh,

      in case you want to upgrade the complete SAP S/4HANA 1709 system to SAP S/4HANA 2020 including the S/4H UIs and backend, then you can do it in one step.

      In case you want to keep the S/4HANA Fiori UIs and the S/4H backend on the older release and you only want to upgrade SAP Fiori front-end server components (SAP_UI and UIBAS001), then you can do the upgrade FES4.0 to FES6.0 on the S/4HANA 1709 system.

      SAP Fiori for S/4HANA 1709 is not released for FES 2020.

      Kind regards.

      Hi Timon,

      The minimum NW version for SAP Fiori front-end server 2020 is NW7.52. This is the reason why an embedded FES deployment is not possible for SAP Business Suite systems, see this section in the blog above:

      For SAP Business Suite systems only the hub or standalone server deployment will be supported with SAP FES 2020 (as of SP01).
      In  case  of  a  standalone server (or hub) deployment, the minimum SAP NetWeaver(NW) release is NW 7.52 SP06 for the initial shipment stack and NW 7.52 SP07 for FES 2020 Sp01.

      Kind regards

      In case of an SAP Fiori front-end server hub deployment all SAP DBs are supported: SAP MaxDB, Sybase ASE and SAP HANA.

      Running SAP FIORI Fiori front-end server as an embedded deployment on your S/4HANA back-end will require SAP HANA database.

      Hello Carola,

      in case of FES 6.0 hub deployment with s/4HANA 2020 FPS 2 as Backend:

      Is it possible to deploy Z UI5 Apps to FES 6.0 and register OData Services while

      the OData Impl. resides on the s/4HANA 2020 Backend?

       

      The OData Version should be v2 in our case and is managed by the creation of the SEGW project

      on the s/4HANA 2020 backend (project type "Service with SAP annotations" - means OData v2)

      - is that correct or is there odata v4 out of the box enabled? How we can set up odata v2 for this scenario?

      Thanks a lot.

      SAP S/4HANA 2020 needs as minimum FES version SAP FES 2020 for SAP S/4HANA. You can use SAP FES 2020 with SAP S/4HANA 1909 or 1809, but not an older SAP FES version with the newest S/4HANA release.

      you wrote

      In case of an SAP Fiori front-end server hub deployment all SAP DBs are supported: SAP MaxDB, Sybase ASE and SAP HANA.

      Is there any (technical) reasoning behind this to axe AnyDB like DB2 for a hub deployment of FES 2020 or FES 2021?

      Any plans to change that to really support AnyDB? After all FES 2020 e.g. supports say product version "FIORI ERP APPLICATIONS X1 1.0" which than contains e.g. "Approve Purchase Orders" where Fiori Apps Libary states "Databaise = AnyDB" https://fioriappslibrary.hana.ondemand.com/sap/fix/externalViewer/#/detail/Apps('F0402')/W13

      BTW:
      Out of curiosity (read: uncertainty) we planned upgrade from an existing FES 6.0 hub on AnyDB (DB2) via Maintenance planner and that worked fine to the step where we can download the stack XML. But then again, it's the maintenance planner after all and SUM might have a totally other opinion about FES 2020 on AnyDB.

      Hi Jens,

      The restriction to an SAP DB is related to SAP S/4HANA Fiori apps, not the SAP front-end server components itself. E.g. refer to SAP note 2935911.

      That means you could install SAP FES 2020 on a hub server with DB2, but not SAP Fiori for S/4HANA on the same.

      Kind regards. Carola

      Hi Carola,

      That's interesting. The note specifically say that for hub deployment only SAP MaxDB, Sybase ASE and SAP HANA Database are supported.

      In our case we have an old classic OracleDB in a hub front-end and we decide to not migrate and stay in FES6 due to this restriction. So, if we decide to migrate, the only real implications are SAP S/4HANA Fiori apps and not the SAP front-end server components itself? I cannot see this specific detail in note 2935911 but would be real good.

      Thanks.

      Hi,

      SAP Note https://launchpad.support.sap.com/#/notes/2935911 describes the dependencies for the SAP Fiori for S/4HANA apps, which require an SAP DB.

      SAP Note 2919182 - SAP Fiori front-end server 2020 for SAP S/4HANA describes the front-end server components, where you cannot find a restriction related to the database.

      Using a SAP FES hub for Business Suite/ERP apps works with AnyDB.

      Hi Carola and all interested folks,

      while it is clear now, that FES (SAP Fiori front-end server 2020 / 2021 for SAP S/4HANA) is not restricted to any database but product "SAP Fiori for S/4HANA" is restricted to SAP databases (read that again, it's also Sybase and MaxDB, not just HANA) I have that bitter feeling that SAP flexes it's muscles to (not so gently) push us to HANA

      I feel that because very few will deploy an FES on say MaxDB when coming from an say Oracle DB but they eventually must deploy an HANA DB for the S4H system anyways. So they will not introduce a (third) DB system but probably stick with either an embedded deployment on S4H or moving the FES to HANA.

      The "bitter" part about that is that it does not seem to be a technical restriction to only support SAP DBs for product "SAP Fiori for S/4HANA" because where would an MaxDB perform better underneath an FES comparing to Oracle or DB2 or...

      I could have understood some (weak) "we could only guarantee performance on HANA"  argument, but to put simply, I don't see the reasoning (besides SAP wanting to bolster their HANA sales) to force SAP DBs

       

      Anyhow, we need to consider deployment options little more in-depth as I would hoped for in an S4H conversion project

      Cheers

      Jens

      Dear Carola,

      We have FES 6.0 as central hub. Does not have HANA-DB. It is connected to 2 different business-suite ERPs.

      Now we upgrade our old HR to Basis-Release S/4HANA 2020 (compatability pack). Reason is getting rid of ESS/MSS (based on java enterprise portal) and switching that to Fiori.

      Could we connect (I know, not recommended) that HR system on 2020 to our FES 6.0? Or would we need to upgrade that FES 6.0 system to 2020 first. But could we upgrade to FES 2020? I think there is no upgrade-path, at least not if we would need to switch to S4 indeed.

      Hello Clemens,

      I guess you could simply link that HR System in your central Hub FES more or less like an external link.

      If you plan to use the HR apps within the FES and then use the HR system as backend --> I guess this is not working, but maybe Carola can spend some more words over here.

      Hi,

      You would need to upgrade to FES2020 on the hub to use S/4HANA 2020 as a backend.

      If an external link from FES6.0 hub to the S/4HANA2020 launchpad is sufficient, than you could keep the FES6.0 as hub. But then you have only a loose integration. For some cases this might be sufficient.

      If not possible, how are ERP clients supposed to use Draft Handling, and CDS functions not available in 7.50? Is there a path other than upgrading to S4, which is not a possibility at this point.

      Hello Carola,

       

      Thank you for the blog. It is a good starting point for Fiori FES deployment. In the above blog you mention the following:

      "In addition, for SAP Business Suite systems, the SAP Fiori front-end server can serve as central hub to offer a single entry point to multiple systems. This is not possible for an SAP S/4HANA system landscape, because of the version dependencies of the SAP Fiori UI components and backend versions."

      From the above  I have concluded the following. Am I correct?

      "For the on-premise S4-2020, the embedded Fiori FES is the only option. FES does not support on-premise S4-2020 in any type of hub configuration. "

      Thank you

      Hi Kiran,

      For an S/4HANA 2020 on-premise  system you still have the option to deploy the Fiori UIs on a standalone front-end server, separate from the S/4 backend.

      But you cannot deploy the Fiori UIs on a central hub and use this to connect several S/4HANA backend servers using the same Fiori UIs. This is because of version dependencies between the Fiori UIs and the S/4HANA backend version.

      Thank you very much for the quick response, Carola.

      We  presently service our external & internal web transactions, including Fiori, via a  SAP Gateway20 and FES40 Hub. I understand we cannot use this topology for S4 even if we upgrade the Hub. So that leaves us the embedded or the standalone options.

      The challenge with going forward with the embedded FES option for S4,  is that my company all ready has a policy of separating ERP and web transactions. But now with the embedded option this extra security layer is eliminated. The challenge with the standalone option as that it seems to double operation tasks, ie, objects need to be in sync with the standalone server as well as the S4 backend.

      Is there a hybrid solution where we switch to the embedded option but still use a "lean" standalone SAP gateway acting only as a security filtering  station ? That way it  would not double  the operational maintenance tasks for the basis personnel. (To me this means the "lean" standalone SAP gateway would somehow not have the FES product  installed!)

      Looking forward to your reply.

      Hi Kiran,

      A lean standalone gateway as you described should be possible. But I wonder, why you then not want to deploy the UIs on this same standalone server  as a FES Hub Deployment. From the Fiori content maintenance perspective I do not see a the double effort.

      Hi Carola,

       

      Thank you for the detailed documentation about recommendations on the Fiori deployment options every SAP customer should know.

      As of today, we have an one standalone/hub FES with one S/4HANA backend system and we are planning to add one more S/4HANA backend system to our landscape in the upcoming phases. Hence we would like to use the same standalone/hub FES setup for the new backend system (the idea is to have all the S/4HANA backend versions in sync at any given point of time in present/future upgrades)  to achieve the common central capabilities like Central Inbox, Central Notifications, Central Search etc., along with deploying all the Business specific Fiori apps centrally. Until we get towards the perfect Central FIORI Launchpad service offered & recommended by SAP on SAP BTP, we would like to reuse our existing one FES standalone/hub to a maximum extent.

      My questions are related to #3 in FAQ section of the provided document (connect several SAP S/4HANA systems of the same release to a central FES). Could you please clarify the below questions from your side and share your view If there are in flaws in the explanations below.

      1. App descriptors: As specified in the FAQ answer, though it is theoretically possible to connect several S/4HANA backends of same version to one FES standalone/hub, each backend system alias for the app descriptors remains the same in both the systems and while replicating them there will be an issue for mapping them in FES uniquely. As these app descriptors are related to only SAP GUI/Webdynpro apps - what if we create our own Alias & mapping for those GUI/Webdynpro apps in scope and replicate them as per our need instead of all Standard content from both backends as specified in the link Mass Maintenance. Hence can we use this solution to bridge this gap until we move to SAP BTP. Do you see any complexities to achieve this setup?
      2. Central Inbox:  As specified in the documentation we can connect multiple S/4HANA backend systems and process all the work Items for a given user centrally in one place without any issue. Do you see any complexities to achieve this setup?
      3. Central Search: we can connect one S/4HANA backend using a proxy approach with another S/4HANA backend and access the central consolidated search results in a standalone/hub FES as specified in the link Multiple Backends Enterprise search. Do you see any complexities to achieve this setup?
      4. Central Notifications: Like the Central Inbox, using the multiple backend system alias, we can register the Notification providers of each backend in the standalone/hub FES and centrally view all the notifications for a given user. Do you see any complexities for achieve this setup?
      5. Platform specific apps: Apps like Custom Fields and Logic, Custom Analytical Queries, Custom CDS views etc., which are common apps with common ODATA services for all S/4HANA systems cannot be accessed centrally. Our idea is to have these app access within the IT team with an embedded FES approach so that we do the configuration independently on each backend system as we cannot deploy them centrally using same ODATA service. However for the wider audience who uses are all Fiori apps are from Business community, we would like to provide the Central FES to Business users for all Business specific apps (Because each Standard Business app/tile will be a one app of one backend with one OData service at a given instance). Do you see any complexities to achieve this setup?

      Kindly comment on the above questions with your recommendations for our plan to use one standalone/hub FES to deploy all type of Fiori apps for multiple S/4HANA backends of the same version to consume the central features until we move to SAP recommended SAP BTP.

      Hi Avula,

      In principle the scenario you describe is possible, but it is not recommended from SAP side. To keep the backend versions in synch at any time in future might be challenging. For the individual topics, let me shortly comment as of my knowledge:

      1. Should be possible, there is some effort to do this.
      2. There should be no issues
      3. Enterprise Search should work. For details on the setup I would recommend to contact an expert from Enterprise Search.
      4. No issues expected
      5. Sorry, I cannot answer. In fact I did not fully understand the requirement.

      In general, maybe you can bridge the gap to a certain extend for a while with some effort. But the recommendation for a multi S4-system entry point is still to use the Launchpad Service on BTP.

      Kind regards.
      Carola

      Hi Carola,

      thank you for the continous updating of this interesting and informative blog and a happy new year.

       

      Do you have any information on support for business suite from new FES 2021 FOR S/4HANA? Is it planned?

      If I see the maintenance times for FES 2020 und FES 2021, it seems, that business suite customers should stay on FES 6.0, right? At the moment after 31.12.2023, customers with business suite and FES 2020 FOR S/4HANA do not have a maintained FES anymore.

      What is your recommendation regarding this? For me it is: Stay on FES 6.0, because it is maintained till the end of business suite.

       

      thanks and best regards

      Christian

      Hi Christian,

      With Business Suite you could stay on FES 6.0 until end of maintenance of Business Suite.

      If you want to consume new UI technology innovations delivered with FES 2020 FOR S/4HANA (e.g. pages/spaces) you can upgrade to the newest available FES, which is FES 2021 currently. SP01 of FES 2021 will be released in February 2022.

      Also for this SAP Fiori front-end server for SAP S/4HANA product, you will get a maintenance version until end of maintenance of SAP Business Suite.

      Therefore, you don't need to stick to FES 6.0. But it's an option.

      Kind regards.

      Carola

      Hi Carola

      Thanks for your explanations.

      We have a standalone FES 5.0 (We must upgrade to 6.0) under Netweaver ABAP 7.50 connected to our Financial ERP 6.0 EHP0.

      Now We want connect our Human Resources ERP 6.0 EHP8 to Fiori, but We are thinking to installed a new FES 6.0  independent of the current Fiori.

      The new FES 6.0 will be used only for SAP Human Resources, not for multiples Business Suites.

      We have doubts whether to install the new FES 6.0 embedded in the HR ERP 6.0 or as a Standalone system under Netweaver 7.50. HR ERP 6.0 is a critical system because it does the payroll calculation.

      What is your recommendation for the new fiori, embedded or standalone?.

      Thanks 
      
      Best regards

      Hi Javier,

       

      even though I am not Carola, I have one answer from my view. In the above linked system landscape recommendations, business suite is still recommended for hub deployment (separated gateway, as your described scenario).

      We still follow this recommendation for our HCM clients. But we also have one client with embedded deployment and running payroll. From my view, separating data and view-logic is the better choice, especially for sensitive data like HCM. But let's see what H4S4 brings...

       

      best regards

      Hi Javier,

      The recommended setup for Business Suite is a hub deployment.

      Either you upgrade your existing front-end server 5.0 to 6.0, where you also could connect your HR system,

      or, if you definitively want to set up a new one for the HR system, then the recommendation would be to set it up with FES 6.0 on SAP NetWeaver 7.52.

      Kind regards. Carola

      Thank you very much Carola

      We are going to try to convince the Finance and HR teams to use the same Fiori FES, after upgrade it to FES 6.0.

      The main problem they see is that the Financial ERP system is  ERP 6.0 EHP0 (waiting to migrate to S/4Hana directly in the next few years) and the HR ERP system is ERP 6.0 EHP8. They want to avoid compatibility issues between FES Hub and backend, but as you say in this blog FES 6.0 mantenance will be until the end of ERP Business Suite maintanance.

      Regards

      Javier

      Hi

       

      Currently, we have deployed Fiori FES as a Hub model and a few custom apps on Sap BTP. As a long-term single entry single sign-on and digital UX strategy, we are evaluating SAP Launchpad and Workzone. my question is if we implement the SAP BTP - Workzone, we want to know what is SAP recommendation on changing the underlying Fiori architecture. Should the HUb deploy be migrated to Gateway Embedded on S/4 and other on-prem apps and use FES/UI on the Cloud platform or should it be a mixed architecture?

      Hi,

      The recommendation is to go for embedded deployment with S/4. This recommendation is valid independent of the usage of SAP Workzone or Launchpad service as entry point.

      Hi Carola,

      thank you for that awesome blog, it's always hard to find the relevant Information and you've mostly aswered als my open questions for our upcoming upgrade.

      But I'm still struggling to understand how to chose the right version for UIBAS001 in our Business Suite Scenario:

      FES (SAP_BASIS 7.52, SAP_GWFND 7.52)

      • Will be upgraded from FES 5.0 to FES 2021 FPS1

      BES (EHP7, SAP_BASIS 7.40, SAP_GWFND 7.40)

      According to the notes (2436567, 3050199) it seems we only have to chose the right version for UIBAS001 depending on our target S/4HANA Backend.

      We might attach our S/4HANA 2020 someday, so i thought about version 600, but currently we need to take care that our business suite system is still compatible.

      I know that a lot of the included apps of UIBAS001 are S/4 only, but will it not also affect the My Inbox (F0862)? Or is this app identically in all versions?

      Thank you!

      Regards,

      Klaus

      Hi Carola,

      today we've tried prepare our setup in the Maintenance Planner for our FES by choosing product FES 2021 SPS1 hub deployment, we see radio buttons to select the target UIBAS001:

      • If we select 600, SAP_UI 755 is automatically chosen
        • 600 would be right, as we might attach a S/4HANA 2020 System one day.
        • I don't think that this will include SAPUI5 1.96, as the latest SP for it was released on 30/09/2021.
      • If we select 700, SAP_UI 756 is automatically chosen. 

      I'm wondering why SAP_UI 755 would get selected, as it's related to FES 2020?

      We would like to check the relevant note 2217489, but it's not available since end of last week, as it's currently getting updated.

       

      What can we do now?  I'd be glad if you gut give me input, thank you!

      First I would like to say thank you for your ongoing effort in clarifying things in the area of FES and S4H / Business Suite. This is a prime example of value added by the community ♥

      However, I wouldn't be here if there was not still something to ask ;). We are in a similar situation than Klaus, wanting to attach an to come S4H 2021 and an existing ERP to a Hub FES 2021 for S4H. IMHO there are these uncertaincies for My Inbox App

      • Fiori Apps Library
        • When selecting Business Suite I will get a Frontend Software Component Version of UIBAS001 500 - SP 0000
        • When selecting S4H if will get a Frontend Software Component Version of UIBAS001 700 - SP 0000
      • Note 2436567 ominously mentions e.g. F2057 - Application Jobs Reuse Library having tight dependency between UIBAS001 and backend system.

      My questions to this are

      1. Is Fiori Apps library for app "My Inbox" just showing the minimum UIBAS001 500 SP 0000 Version for an Business Suite or is just not meant to be interpreted that way?
      2. Will Note 2436567 evolve in that "central note" when it comes to restrictions about running UIBAS001 with a different backend version that it originally shipped with (e.g. UIBAS001 700 <-> S4H 2021 is fine, UIBAS001 600 <-> S4H 2020 is fine but UIBAS001 700 <-> ERP might have some restriction on specific apps?). In other words: If in 2436567 no restrictions are mentioned, I can assume I'm fine?
      3. Ultimately: Am I right that I'm supported to have the same UIBAS001 700 on the FES HUB when looking at "My Inbox" both for S4H 2021 (FPS1) and Business Suite (ERP EHP8 + HCM on ERP EHP8)

      Many thanks and kind regards and (kind of) sorry for all that questions, but it seems I'm not the only one 🙂

      Hello Jens,

      1. FES6.0 (including UIBAS001 500) is the minimum front-end server version which is in maintenance. You also could use FES2020 or FES2021 as hub for the Business Suite system.
      2. I would say "Yes". Restrictions should be mentioned in this note.
      3. Yes.

      You are welcome with all the questions 🙂

      Kind regards.

      Hi

      What happens to user-developed custom Fiori if I upgrade my S/4HANA1809 to the S/4HANA2021?

      Can I continue to use the custom-developed Fiori as it is?

      If a refurbishment is needed, what tool can I use to investigate the refurbishment?

      Hi Carola / all

      • we want to upgrade our current FES 6.0 on AnyDB to a FES 2021 for S/4HANA on HDB.
      • we have a hub deployment
      • we want to stay on the hub deployment and the target state would be: One S/4HANA 2021 FPS 1 and several business suite systems (one being an HCM ERP EHP8) attached to the hub.
         
      • I was under the impression that with FES 2021 for S/4HANA we will also go to SAP S/4HANA FOUNDATION 2021
      • However, I found misleading information on what is supported:
        • https://launchpad.support.sap.com/#/notes/3015497 says

          "SAP FIORI FES 2021 FOR S/4HANA - SAP Frontend Server 7.56 (not to be used as a Fiori Frontend Hub system but only as a basis in case of an embedded installation)"

        • https://launchpad.support.sap.com/#/notes/3085560 says

          For SAP Fiori front-end server 2021 for S/4HANA, both deployment options - embedded and hub (standalone server) - are supported. The embedded deployment is recommended. In case of a standalone server deployment, the minimum SAP NetWeaver release is SAP NetWeaver 7.52 SPS08.

      What is right now?

      The whole "what is supported in which condition for the FES itself, the "UI-Product" (like SAP Fiori for SAP S/4HANA 20nn) the SAP S/4HANA Foundation 20nn, the SAP_UI dependencies and on top the product specific dependencies (like FIORI ERP APPLICATIONS X2 1.0, etc.) is nothing short of a snakepit - filled with sharks with laser beams attached to their heads.

      Hi Jens,

      There are several options to install SAP Fiori front-end server 2021 for SAP S/4HANA.

      The front-end server hub is always based on SAP NetWeaver 7.52.

      With an embedded FES deployment with SAP S/4HANA you have the corresponding ABAP Platform version as a basis.

      See SAP Note https://launchpad.support.sap.com/#/notes/3050199.

      Further information you can find here:  SAP Fiori deployment options and system landscape recommendations.

      Kind regards. Carola

      Thanks Carola 🙂

      So my takeaway would be to go for SAP NetWeaver 7.52 based  SAP Fiori front-end server 2021 for SAP S/4HANA (SPS 1) to serve both an to be SAP S/4HANA 2021 FPS1 and an existing Busines Suite environment, e.g. HCM based on ERP EHP8.

      Hi,

      even if it's currently technically possible to set it up in this way, this is not a recommended/supported deployment option. It's also not a forward-looking setup, because SAP Business Suite support might be not given for future SAP Fiori front-end server versions.
      Kind regards.

      If we are going with mixed/hybrid, like Hub approach for business suites systems and embedded approach for S/4 Hana and  try to call fiori apps of S/4 Hana via URL in Hub launchpad, will it support in-place navigation?

      Hi altogether,

      according to the last questions of Matt D above for that mixed scenario: If we like to have a full on premise scenario (business suite, S/4 and hub gateway in our own data center), there is no way of centralising ERP-S/4- and e.g. HCM-Business-Suite Fiori apps in one launchpad?

       

      If I am reading the PDF document correct, in this mixed scenario, you will add a tile on the central hub Fiori launchpad, besides the HCM business suite Fiori apps tiles. This tile then links to the Fiori launchpad of the embedded S/4-sytem. Is there still no alternative for such a mixed scenario for on prem for a real central Fiori launchpad?

       

      If not on prem: Are Work Zone and Launchpad Service real central alternatives for such a mixed scenario?

       

      thanks and best regards

      Christian
