We are trying to use EXIT_SAPLATPC_002 to update the delivery date in purchase orders according to customer business logic, i.e. we want to use a different delivery date than the one SAP would suggest. The transaction is V_V2 (Rescheduling).
We already tried to update the fields DAT0x in the tables T_ATPCSX and T_MDVEX, but didn't get the results we were looking for.
Has anyone used this user exit to change the PO delivery date and if yes, how?
