Hello Kai,
I think you require an implemented association for that as the field containing the link information is located on the foreign BO. However, this is not a big thing:
1. Create a non-unique altkey on the BOB's "ALICE_KEY" field (if it is not already there)
2. In the implementation of the resolve method of the association just use the Service Manager's CONVERT_ALTERN_KEY Service to resolve the target keys in the implemented association:
- IV_ALTKEY_KEY: Constant for ALICE_KEY altkey
- IV_TARGET_ALTKEY_KEY: /BOBF/IF_FRW_C=>SC_ALTERNATIVE_KEY_KEY
- IT_KEY: IT_KEY that are the instances of the alice
Best regards
Tilmann
