Double Ordered Part Received To Order Line - How to "Unlink"?

An end user notified me that the purchasing team double ordered a specific part on a sales order line, it wasn’t caught and eventually 2 PO lines were received to the same sales order line. Let’s say Order Line had Qty 1 for Part ABC, 2 separate PO Receipts for Qty 1 each were done and then invoiced and posted already.

Since they only needed Qty 1 for that line, I have been asked to “unlink” one of the received qty’s so that it can be moved to inventory Qty-On-Hand and used by inventory to fulfill other demand.

What is the best standard practice for “un-linking” or un-allocating 1 of the received Qty’s from the sales order line so that it can be used by inventory for other demand?

Thank you very much for reading.
