How to Find BAPIs Used in SAP_TC_PRC_COMMON?

Since Technical Catalogs primarily deal with Fiori applications and OData services, BAPIs are usually called via these services. Here's how you can find the BAPIs used:

1. Find Applications and OData Services in the Technical Catalog

1. Go to SAP GUI and open transaction /UI2/FLPCM_CONF (Fiori Launchpad Content Manager).
2. Search for SAP_TC_PRC_COMMON in the Technical Catalogs section.
3. Click on the catalog to see the list of apps, transactions, and OData services it contains.
4. Note the OData service names used in the apps.

2. Identify the Backend OData Service in SAP Gateway

1. Open transaction /IWFND/MAINT_SERVICE in SAP Gateway.
2. Search for the OData service(s) you found in step 1.
3. Select the service and navigate to the Service Implementation tab.
4. Look for the Entity Sets and their associated ABAP Class/Methods.

3. Find the BAPIs in the Backend Implementation

1. Once you find the ABAP class in the OData Service, go to transaction SE24.
2. Enter the class name and check the methods.
3. Look for CALL FUNCTION statements in the method implementations to find the BAPIs used.
4. You can also check the CDS views that might be exposed through OData.

4. Alternative: Search for Standard BAPIs in SE37

If you are unsure which BAPIs are used, try:

1. Transaction SE37 – Search with BAPI_* keywords related to procurement.
2. Transaction SE80 or SE93 – Find the backend transactions used and check their associated function modules.
