Payables closes a purchase order when the quantity billed and the quantity received (if you require receipt on the purchase order shipment) against the purchase order are both greater than or equal to the quantity ordered less the quantity cancelled on the purchase order.
Payables displays a warning message if you try to match to a closed purchase order, but you can still complete the match unless the shipment is finally closed. When you submit Invoice Validation, Payables applies the appropriate matching hold(s). You can reopen a closed purchase order in Purchasing by adding a new shipment, over-receiving within your tolerance, or changing the quantity for a shipment.
Payables closes a purchase order shipment when the quantity billed and the quantity received (if you require receipt on the purchase order shipment line) against the purchase order shipment are both greater than or equal to the quantity ordered less the quantity cancelled on the purchase order shipment.
In Oracle Purchasing, you can manually close a purchase order at the header, release, line, and shipment levels and also enter a Closed Reason, which is displayed in the Match to Purchase Order and Match to Receipts windows. This indicates that the record was intentionally closed and should not be matched. For detailed information, see: Oracle Purchasing User Guide.
Note: The Finally Closed status of a purchase order indicates that the purchase order is permanently closed and no further actions can be performed against it in either Purchasing or Payables.
