I finally managed to receive a list of all existing BAPIS/RFC from SAP using a proxy of RFC_FUNCTION_SEARCH created with NCo 2.0.
I tried the same with RFC_GROUP_SEARCH to get the hierarchy that I can see in my SAPGUI when I'm in the BOR (Transaction "BAPI").
What's strange: The groups RFC_GROUP_SEARCH returns are totally different from the ones in the Business Object Repository (BOR).
Can someone please tell me how I can get this hierarchy out of SAP using NCo 2.0?
Thanks in advance,
