User Interface technology at SAP has a long history. Starting with SAP GUI, Business Server Pages (BSP), Web Dynpro, Floorplan Manager (FPM), Enterprise Portal (as a client for UI integration), we have now Fiori.

Fiori apps are web applications, which need a SAPUI5 library and a Fiori Launchpad and last but not least an “SAP Fiori Front-end Server” on which all runs on premise or need SAP Fiori Cloud for cloud deployment.

Classic SAP GUI and Web Dynpro applications using SAP Fiori theme need an AS ABAP in the backend, which supports SAP Fiori theme. This is only the case for AS ABAP 7.51 and higher for S/4HANA.

 

What is SAP Fiori Front-end Server?

First of all, it is just an Application Server ABAP.

 

Technically it is an Add-on to AS ABAP, delivering the right Service Pack Stack (SPS) definition (stack.xml) for AS ABAP, suitable for Fiori App deployment.

 

Figure: Schematic representation of SAP Fiori Front-end Server

 

 

Each SAP Fiori Front-end Server (FES) supports multiple AS ABAP versions, basically starting from AS ABAP 7.40.

FES version AS ABAP 7.40 AS ABAP 7.50 AS ABAP 7.51 AS ABAP 7.52
FES 2.0 x x
FES 3.0 x x x
FES 4.0 x x x x

 

FES defines the initial shipment stack (ISS) and service pack stack (SPS) for 2 AS ABAP software components independent from the AS ABAP stack.

  • User Interface Technology (technical name “SAP_UI”) and
  • SAP Gateway Foundation (technical name “SAP_GWFND”, only up to AS ABAP 7.51).

Means SAP_UI can be upgraded (new version) or updated (higher SP) independently from the underlying AS ABAP stack definition. SAP_GWFND can be updated independently from the underlying AS ABAP (up to 7.51 including).

 

The SAP Fiori Front-end Server version always defines exactly one version of SAP_UI. SAP_UI contains the innovation version and one maintenance version of the SAPUI5 library.

For example:

FES version contains SCV contains
FES 2.0 SAP_UI 7.50 SAPUI5 1.38.x
FES 3.0 SAP_UI 7.51 SAPUI5 1.44.x
FES 4.0 SAP_UI 7.52 SAPUI5 1.50.x (Innovation, planned maintenance vers. 1.52.x)

(For more information about versioning, see versioning of SAPUI5, and available SAPUI5 versions)

 

FES defines also the SAP_GWFND up to AS ABAP 7.51. The SAP_GWFND software component version has always the same version as the underlying AS ABAP but shares the Service Pack Stack definition with SAP_UI, which is defined in FES.

From AS ABAP 7.52 on, SAP_GWFND is not anymore part of the FES stack definition and can  be updated independently from the FES (and AS ABAP) stack definition.

 

FES version SAP_GWFND 7.40 SAP_GWFND 7.50 SAP_GWFND 7.51 AS ABAP 7.52
FES 2.0 x x
FES 3.0 x x x
FES 4.0 x x x x

 

Two additional Components

FES contains additionally the SAP software component “UI for Basis Applications“, the technical name “UIBAS“. In documentation, it is named “SAP Fiori Apps for SAP NetWeaver”. The target group is “key user for SAP NetWeaver”. These apps are mainly required for some S/4HANA Fiori apps and are only available for FES on NW AS ABAP 7.5 or higher.

100-300 for S/4HANA.

FES version contains available for AS ABAP
FES 2.0 UIBAS 100 7.50
FES 3.0 UIBAS 200 7.50, 7.51
FES 4.0 UIBAS 300 7.50, 7.51, 7.52

The second additional component is SAPUIFT 100 (only one version available, SP01 max.). This component is deprecated.

 

 

Maintenance and Update

Thes FES Add-on also provides the 2 software components “SAP_UI” and “SAP_GWFND” independent AS ABAP. So these 2 components can be downloaded and implemented or updated independently from the AS ABAP stack definition.

The FES stack definition can run a higher SPS than the underlying AS ABAP SPS. E.g. if you update FES 3.0 to SPS09, typically SAP_UI and SAP_GWFND (until 7.51) will be SP09, while e.g. SAP NetWeaver 7.5 can – but need not – stay on SPS01.

 

 

Upgrade

As ABAP allows you to upgrade the SAP_UI version to a higher version. e.g. AS ABAP 7.50 allow to upgrade SAP_UI 7.50 to SAP_7.51. FES does not. In this example, you have to upgrade from FES 2.0 to FES 3.0.

If you want to “upgrade” your SAP_GWFND to a higher version, you have to upgrade the underlying AS ABAP to a higher instance. The highest possible SAP_GWFND and AS ABAP version is the SAP_UI version.

 

 

 

Deployment Options for SAP Fiori Front-end Server

SAP Fiori Front-End Server allows various deployment options.

  • Embedded deployment: The front-end server is deployed into the (existing) AS ABAP of a Business Suite or S/4HANA backend system.
  • Hub single backend deployment: A dedicated AS ABAP based SAP Fiori Front-end Server is deployed “in front of” the backend system. These allow decoupling of the life cycle of the AS ABAP of the FES from the AS ABAP of the backend. Different backends run in different AS ABAP clients of the FES. Fiori apps for different backend versions do not interfere each other.
  • Hub multi-backend deployment: Deployment in one FES client for multiple backends. Only possible, if the software components for the Fiori apps are different and do not interfere each other.

    Hello Oliver,

    We have a central hub gateway system running on NW 750 SP0009 (SAP_UI and SAP_GWFND both on 750 SP0009).

    We want to know whether we can have the SAP Belize theme for launching classic Web Dynpro ABAP tiles from the Fiori launchpad without upgrading the SAP_UI component to version 751.

    Regards,

    Saurabh

    • Hub multi-backend deployment: Deployment in one FES client for multiple backends. Only possible, if the software components for the Fiori apps are different and do not interfere each other.

    Meaning I cannot have a single FES with Fiori Launchpad to link to the same Fiori app (two tiles with different target alias) on different backend systems? What is your source for this?

      no, it means that you cannot deploy two different software component versions of the same software component in one AS ABAP. And Fiori Apps are delivered as AS ABAP software components.

      You can use external links.

    Hello Oliver,

    Currently what I understand is that FIORI Launchpad Site can be deployed on HANA XS directly from SAP Web IDE. Then we do not need ‘SAP NetWeaver AS for ABAP’ for running FIORI Launchpad on HANA XSA, since HANA XSA is the run time environment for Fiori Launchpad and FIORI Front End Server is not required. Is this understanding correct ?

    If yes, then what would be the FIORI version and how can we use features of FIORI 2.0 such as Notification Centre.

    Best Regards,

    Shivam

    FLP is available on many platforms. In general FES or SAP Fiori Cloud is required if you want to deploy SAP Fiori apps from SAP. For  a list see Fiori Apps Library.  I am not aware of any apps, which only need HANA XS and FLP, but I dont know all of them. Best you check the implementation information for your Fiori apps. Notification always require Gateway foundation 7.51 or higher (docu). Again, could be that there are meanwhile also other implementations, My focus is FES.

    For custom development of Apps, using Fiori themes and/or design principles, you are of course free to setup your landscape as you need it.
