Invoice Message problem

Legacy Contributor

We had an item on a PO (Special) be received, matched which created an invoice message. The message was answered : Disapprove - Reason: Do Not Pay, which left the invoice in a pending status.
I tried to change this to: Chargeback - Y, Do not Pay.
Lawson gave me an error saying: Can not chargeback, MNR Qty has been received. How do I correct this?

Have the AP reverse match the invoice and rematch.
