RE: Change incorrect invoice number on posted receipt?
Hi SJacobs,
The invoice number is a part of the voucher and as such it cannot simply be changed subsequently.
You have to post a corrective voucher/invoice.
If this involves too much work and if you are fine with the number used from a system perspective then it might be sufficient to post a note in attachment of the invoice.
Otherwise, you would have to create a reversal and then post a new invoice again. As this is related to a PO you will have additional inventory transactions and some more work.
Best regards
Ludwig
