SAP Fiori deployment options and SAP Fiori front-end server strategy – UPDATE 2020

You already might have heard about the extended maintenance period of SAP Fiori front-end server 6.0 as a long-term, stable UI technology foundation for SAP Fiori apps of SAP Business Suite and SAP S/4HANA systems, described in this blog post.

But what is planned beyond and what is SAP’s strategy regarding the SAP Fiori front-end server and the recommended deployment options?

This blog post delivers a short summary. For more details, please check out the updated version of the SAP Fiori deployment options and system landscape recommendations.

Today the SAP Fiori front-end server 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.

Outlook 2020

SAP plans to deliver the new SAP Fiori front-end server 2020 for S/4HANA for the latest three SAP S/4HANA releases: 1809, 1909 and 2020. For support and strategic reasons SAP Business Suite and lower SAP S/4HANA releases will not be supported.

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

As shown in the graph, you will be able to upgrade the front-end server component to SAP Fiori front-end server 2020 for SAP S/4HANA for 1809 and 1909 systems, without upgrading the S/4HANA product version. This is valid for the embedded and for a standalone server deployment.

Technically SAP Fiori front-end server 2020 for S/4HANA requires 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.

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

SAP Fiori front-end server 2020 for SAP S/4HANA does not support SAP Business Suite systems. For SAP Business Suite systems an upgrade to the long-term maintenance version SAP Fiori front-end server 6.0 is recommended. Please refer also to this blog post.

In consequence, the scenario with a central front-end server hub with one SAP S/4HANA system and one or several SAP Business Suite systems connected (the so-called “mixed” scenario) is no longer supported with SAP Fiori front-end server 2020 for S/4HANA. An upgrade of a connected SAP S/4HANA system to SAP S/4HANA 2020 then would mean, that it has to be disconnected from the central hub. For this SAP S/4HANA 2020 system it’s recommended to apply the embedded front-end server deployment. An alternative might be a dedicated standalone front-end server.

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 central front-end server hub as a single entry point to multiple systems with the required UX integration capabilities is planned to be covered by the central SAP Fiori launchpad on SAP Cloud Platform, which will evolve further 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,

    Rupesh

    • 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

      Carola

  • 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,

    Timo

    • 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

  • 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

  • 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.

    Wladimir

    • 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.

      Kind regards.

      Carola

  • 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.

      Carola

       

      • 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 😉

  • Thank you Carola for the detailed info.

    Is there any possibility of getting new Dark theme for FES 6.0 installed Business Suite ?

     

    Regards

  • Hello Mrs Steinmaier,

     

    are any new news to this topic ?

    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.

     

    Best regards

  • 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
