Hi @BLLBrucemo ,
Yes, it is the standard design that PO header status becomes closed when goods are received.
Further, when it comes to checkbox parameter “Create Postings for Receipt of Non-Inventory Purchase Order Lines” It decides whether postings should be created upon receipt of non-inventory purchase parts or upon no parts in the purchasing flow.
This check box is selected initially when creating the ARR-NONINV receipt transaction, and also when creating return or scrap transactions from the receipt. When matching a supplier invoice the system will also check if postings were created upon receipt and if not, only the M93 posting will be created. If the check box is cleared, then it implies that no cost is booked for the non-inventory or no parts until the invoice is received and matched. This checkbox does not have any connection with the status of PO header also.
