How to cancel a return Purchase order???

We received a wrong item. it was accepted by mistake and then we decided to return it…we made a return PO and shipped it (only the system). then, we decided to keep it… the problem is we can not cancel the RPO since there is qty in the QTY reteur shipped.

any solutions?

Just create another purchase order. You can do the same number with a “-A” on the end. Depending on your version you can also Undo Shipments and Receipts from their respective documents.
