The final invoice flag (Field EREKZ) indicates that the final vender invoice for a line item has already entered the system or that additional invoices are no longer expected.

The table /WMD/FP_IVPO and the structure type /WMD/FP_IV_ITEM has been supplemented with the field EREKZ. The field value EREKZ is transferred to the BAPI module when the document is parked or posted.
