Guidance to trace FIORI Apps in SAP GUI

BY-STEP: Trace a Fiori App

✅ Step 1: Identify the App from the Tile

1. Open the Fiori Launchpad.

2. Right-click the tile > Inspect (in Chrome DevTools).

3. Find the #-based hash URL:

   php-template

   CopiarEditar

   #<SemanticObject>-<Action>

   Example:

   arduino

   CopiarEditar

   #Material-display

4. Take note:

   • Semantic Object = Material

   • Action = display

✅ Step 2: Get App Configuration via App Descriptor

Transaction: /UI2/FLIA

1. Enter Semantic Object = Material, Action = display.

2. You will see:

   • App ID

   • App Type (SAPUI5, URL, WDA, etc.)

   • OData Service

   • Component Name

   • Catalog(s)

You can double-click the Application or Catalog ID to drill into more details.

✅ Step 3: Identify the SAPUI5 App

Transaction: SE80

1. Go to: BSP Application → Enter App ID (e.g., /SAP/MM_PO_APV).

2. Look inside folders:

   • Pages with Flow Logic → index.html or Component.js

   • js → contains controller files

   • view → XML views

You now have the UI5 frontend logic.

✅ Step 4: Get the OData Service and Metadata

Transaction: /IWFND/MAINT_SERVICE

1. Search for the OData Service from Step 2 (e.g., MM_PUR_PO_MAINT_SRV).

2. Select it and click SAP Gateway Client.

   You can:

   • View /$metadata (to see entity sets and structures)

   • Test endpoints (e.g., PurchaseOrderSet?$filter=...)

✅ Step 5: Find the Backend Implementation

Transaction: SE24 or SE80

1. Go to backend system (if different from frontend).

2. Enter the Model Provider Class or Data Provider Class (from the OData service).

   • Usually named like ZCL_*_DPC_EXT.

   Check:

   • GET_ENTITY or GET_ENTITYSET methods

   • CREATE, UPDATE, DELETE if used

This is the actual ABAP logic handling the Fiori app.

✅ Step 6: Analyze Authorization / Role Assignment

Transaction: PFCG

1. Search the catalogs (from Step 2) in roles.

2. Check which roles are assigned to users.

3. You can also inspect:

   • Tile/Target Mapping in the Role Menu

   • Semantic Object + Action config
