Corridor - Rejection Notification: Errors: "DUPLICATE INVOICE DETECTED FOR THIS VENDOR!"

An invoice with this number was already successfully submitted to the client.

Corridor Support does not have access to client databases, so you will need to contact the client directly to request that they remove the first invoice so that you may submit the second one. 

Please be aware that if they reject the invoice and do not delete it from their system, you will need to submit the revised invoice with a different number because the original invoice number will still be in their system. You may want to submit it with a suffix to make it a different number (i.e., #1234REV).
