Hi Ajay,
Thanks for reply. Table VBAK holds contract number in reference document field but that is once sales order is created and saved. I tried table lookup on this but since sales order number is not available during order creation, it does not trf to PA segment.
Can you help me to understand what we call in user exit that allows to push to PA segment during sales order creation mode.
I understand there are three components in exit COPA0001 but not sure which component and what code we write there to push to PA segment.
also, I see other characteristics (product, sale div etc) are update in PA segment under account assignment tab but not sure how that auto derived by system.
Best Regard
Sanjay D
