Receipt Routing - Processed and Paid

We have a situation where an item went through the JDE receipt routing program:

Items were all receipted and issued but 2 of the 10 items were returned

• Item Receipted (stock updated)
• Item voucher matched
• Item fully paid

I know that at this point I can do nothing to reverse this receipt back into the route

This is what I think should happen but is hoping some can advise:

• Create a credit for the amount that was incorrectly receipted
• Stock that has been issued needs to be sent back and “adjusted” out of stock

The question here is how do I get these 2 items back into the receipt route – other than creating an additional line on the PO and receipting back into the route.
