Revise Qty on PO lines after a receipt because we are short shipped
As we order a Qty. the vendor ships a partial and then we need to adjust the Qty. ordered after the receipt of the partial on the PO and we are unable to change. We have several line open that are done this way and it hang out there on the outstanding commitment report and Expedite reports. Example is PO 26375 line 4 they are going to ship the balance due 4 ft short and close the PO on their end and it will leave the po open for 4 ft.
What is the recommended process to do the above?
