Hi Horst,
The same issue applies for Reference Association.
I tried to create a Reference Association in order to filter information from BO Promotion->BusinessTransactionDocumentReference
The reference is created, however when I try to bind it the following error is generated during activation:
XRepositoryException (4)Create Behaviour of attribute 'ID1' expected to be 'NEVER' for secondary bindings with target condtions (fragment 'DUMMY_SADL_BO_UUID')
I will create an incident about this. If you have any additional suggestions or maybe a workaround which would not require to create an additional extension field on BO to replicate data, please let me know.
Best Regards,
Fernando Mendel
