Overview


Here we will try to summarize standard Fiori App implementation step by step.

SAP Fiori is a new user experience (UX) for SAP software and applications. It provides a set of applications that are used in regular business functions like work approvals, financial apps, calculation apps and various self-service apps.

SAP Fiori Apps can be accessed on desktops, Mobile or tablets. These are web-based applications hosted on SAP-Fiori server (front-end system) and access business data from SAP-ECC (back-end system).



Please note: In case of SAP-Hana server, Back-end/front-end system is same system.

There are two types of SAP-Fiori app implementations:



  1. Standard Apps

    • Implementation of those business apps, which are released by SAP. These are categorized as Transnational, Fact-sheets and Analytical apps etc.



  2. Customized Apps



Pre-requisites:



  1. SAP ECC Server (Back-end)

  2. SAP Fiori Server (Front-end)

  3. SAP Fiori Launchpad Url:


  4. SAP Fiori Designer Url:


  5. Important T-codes













































    • SrNo T-code Description
      1 SICF  (Path: /sap/bc/ui5_ui5/sap/) UI5 Application Path
      2 SICF  (Path: /sap/opu/odata/sap/) Odata Service Path
      3 /n/iwfnd/maint_service Odata Service Registration
      4 /n/UI2/SEMOBJ_SAP Semantic objects by SAP
      5 /n/iwfnd/error_log Error Log
      6 LPD_CUST Launchpad Role
      7 PFCG PFCG Role





 

Standard SAP Fiori App implementation steps:


Source of App Implementation Details:

Each standard Fiori app consist of below components:

  1. Software Components

    • Back-End Software Components

    • Front-End Software Components



  2. Back-End Components

    • Odata Service

    • Back-End Authorization Role (PFCG)



  3. Front-End Components

    • SAP UI5 Application

    • Odata Service Registration

    • Business Catalog

      1. Tile

      2. Target Mapping

      3. Semantic Object

      4. Launchpad Role



    • Business Group

    • Front-End Business Role (PFCG)





  • Relationship between Front-end components can be understood with help of below image:



 

Example: App Implementation: "Approve Purchase Order"


Lets take an example of standard App Implementation: "Approve Purchase Order"

  1. Get Component details from below implementation link of app "Approve Purchase Order"



  2. Software Component installation



    • Get front-end/back-end software component details of app and take help of Basis team to install in respective system

    • Post-installation cross check software component availability in respective system:

      • Go to SAP Logged in main page -> Menu ‘System’ -> ‘Status’ -> ‘SAP System Data’ -> ‘Product Version’ click on button ‘Component’ -> Check Component






  3. Enable App for Access in SAP Fiori Launchpad




    • Front-End Server: Activate ICF Services



      • Activate SAP UI5 Application

        • T-code: SICF

        • Path:     /sap/bc/ui5_ui5/sap/mm_po_apv



      • Activate Odata Service

        • T-code:  SICF

        • Path:     /sap/opu/odata/sap/gbapp_poapproval/



      • Go to respective paths -> right click -> Activate




    • Front-End Server: Register Odata Service



      • Pre-requisites: System Alias Maintainance

        • In SAP-Fiori (Front-End) System, configure 'system alias' Alias for SAP-ECC (Back-End) System.

          • Go to T-code 'SPRO' -> 'SAP Reference IMG' -> SAP Customizing Implementation Guide -> SAP NetWeaver -> SAP Gateway -> OData Channel -> Configuration -> Connection Settings -> SAP Gateway to SAP System -> Manage SAP System Aliases


          • Enter RFC-Destination and check boxes 'Local GW' & 'For Local App' should be unchecked

          • RFC-Destination should have enabled 'Current-User' logon settings







      • Odata Service registration:

        • T-Code:  /n/iwfnd/maint_service

        • Steps to register:

          • Go to above t-code -> click on button 'Add Service' ->


          • in next window select Back-end system alias -> click on display button 'Get Service'


          • To add service, select service row from grid -> click on button 'Add Selected Service'


          • Next One pop-up comes, where select package as $TMP -> click ok




        • Once service gets registered, we can see it in registered service list of t-code '/n/iwfnd/maint_service' havine zprefix in name as 'ZGBAPP_POAPPROVAL'







    • Front-End Server: Fiori Designer object verification

      • Go to Fiori Desginer url


      • Checking Business Catalog, Tile and Target Mapping

        • Check availability of 'Business Catalog and Tile 'Approve Purchase Orders'


        • Click on Tile ''Approve Purchase Orders',

        • next window has configured semantic object as 'PurchaseOrder' with action 'approve'


        • 'Target Mapping'

        • click Tab icon 'Target Mapping' -> select entry with semantic object 'PurchaseOrder' and action 'approve'


        • Click on status bar button 'Configure' to view configured details in selected target mapping


        • Here we can see configured Launchpad Role 'UIX01MM' having alias 'ApprovePurchaseOrders'












    • Checking Launchpad Role

      • we can verify from SAP-Fiori's t-code LPD_CUST


      • As we can seen UI5 Application path in abaove screen

      • Thus we can summarize, how objects linking as:

      • Business Catalog -> Tile -> Semantic Object -> Target Mapping -> Launchpad Role -> UI5 Application




    • Checking Semantic Object

      • Semantic Object availability can be check in front-end server t-code '/UI2/SEMOBJ_SAP '








  1. Role assignment to user-id



    • Back-End Authorization Role

      • In sap-ecc assign role 'SAP_MM_PO_APV_APP' to user-id for e.g. 'user1'



    • Front-End Authorization Role

      • Here user-id 'user1' will have access to two PFCG role, which are:

        1. App's Front-End Business Role 'SAP_MM_BCR_BUYER_X1'

        2. A custom PFCG Role named as 'Common_FioriApp_Role', which is required for FioriLauchpad page accessibility, having below object access:

          • R3TR IWSV /UI2/PAGE_BUILDER_PERS 0001

          • R3TR IWSG ZPAGE_BUILDER_PERS_0001

          • R3TR IWSV /UI2/INTEROP 0001

          • R3TR IWSG ZINTEROP_0001

          • R3TR IWSV /UI2/LAUNCHPAD 0001

          • R3TR IWSG ZTRANSPORT_0001




        3. Some times, while accessing app, we got Odata Service error, which can be checked in t-code '/n/iwfnd/error_log', if this case arises, then we need to create a pfcg role which will have TADIR Service access of app "Approve Purchase Order"

          • To create a new PFCG role, Go to T-code PFCG -> Enter name -> Tab 'Menu' -> click on button 'Transaction' -> 'Authorization Default' -

          • -> in new pop-up window select 'TADIR Service' -> R3TR -> IWSG SAP Gateway: Service Groups Metadata -> Service from F4 help












  2. Apart from this, perform configuration tasks in the back-end system as mentioned in document link:
