How do I know if a supplier invoice was converted from a purchase order?

Question

How do I check if a supplier invoice was converted from a purchase order?

Answer

Supplier invoices that were converted from a purchase order are flagged with a PO Notice and reference the original PO number.

If your supplier invoice doesn't have PO Notice and the Original PO field is blank, it was likely created from the supplier invoice section and not converted from a purchase order.
