Hi Kees,
we had the same issue . SAP set the billing relevance to J for NCRN where we think this is wrong and we set it to D.
J to our point of view makes only sense for plants abroad with the stock transfer within one company code.
--> our issue: IC stock transfer return with 2 european countries --> same error message
please check the 2 billing status in the delivery:
with J : we had A for billing status and C for Intercompany billing status (after the IG)
--> the A is the reason for the error message as we also have no copy control for F2 set up
then we deleted the delivery and changed the billing relevance to D for NCRN
with D: we had "blank" for billing status and everything was fine
hope this might help you - or in case you have another solution in the meantime I would also be interested
kind regards Angela
