Your company Invoice Policy is set to recognise possible duplicate invoices on submission.
Please Note: All yellow Policy Issue warnings can be ignored by clicking Continue.
There are two ways a possible duplicate invoice is identified:
1) With Invoice Reference: If an Invoice Reference is populated, the system will look for any other invoices with the same Invoice Reference for the same supplier.
2) Without Invoice Reference: If no Invoice Reference is populated, the system will look for any other invoices with the exact same date and amount for the same supplier.
