I am working on an Transaction Import for the Receipt/Invoice Screen in the PO module. It largely works except for one glitch: the Duplicate Invoice screen pops and leaves the import in a suspended state. This should happen when an invoice number is entered on the Invoice Information screen and the invoice number entered matches one previously entered for the vendor. In this case however, none of the invoice numbers are duplicates. I've tried it several times with very unique invoice numbers and the Duplicate Invoice screen always pops.
Interestingly, the import seems to work. No matter how many documents I have in the data file, all are created by the transaction import, but it will not complete because of the Duplicate Invoice dialog. This indicates that it always happens on the last document record regardless of the invoice number.
Any suggestions on how to resolve this?
