Generating purchase order exceptions

You can allow the Planner to allocate supply from a purchase orders to a demand even if the purchase order’s due date is later than the demand's need date. Enable this feature by enabling bit2 (Allow purchased item supply switching) and bit7 (Generate purchase order exceptions) in the ALTPLAN.SSFLAGS field. When the Planner allocates the supply, it assumes you will move in the due date for that purchase order record. An exception message will be generated in the POEXCEPT table.
