If an invoice is matched to the wrong purchase order, you can unmatch it and match it to a different purchase order.

1. On the left panel, select Invoices.
2. On the New page, to help you locate the invoice you want to open, use the Search and / or Filter options. A useful filter is PO Matched = Yes.
3. In Card view, select the invoice you want to open. In Table view, in the Invoice # column, select the invoice # link.
   The invoice opens in the Invoice dialog.
4. In the dropdown field at the top of the dialog, the existing PO # is displayed. From the dropdown, select a different PO.
