If your company has applied the duplicate invoice detection policy rule to your account, then the system may flag or block certain invoices on submission if they're deemed as duplicates.
If you see a yellow policy message, you may click Ignore & Continue to continue with your invoice submission. In this case, your invoice will be reviewed by your approver and/or company Finance team.
If you see a red policy message and the invoice is not a duplicate, you'll need to click Back and won't be able to submit your invoice until you've consulted your company's Finance team and received instructions on how to proceed.
How the system identifies a possible duplicate invoice
A duplicate invoice is identified where an invoice has the same Invoice Reference as another invoice in the system with the same Supplier.
