Following is the requirement:-
1. The business partner will be created in FPP1 and replicated as SD customer.
2. The posting for the business partner would happen both in FI-CA and FI-AR depending on the business process.
The SD/FI-CA integration happens when the account group of the SD customer is ticked in customizing.
When this is done the contract account feild becomes mandatory in the sales order.
Is there any standard way to do this, Please help/suggest.
