Sage 100 Sync Error - Code CI_Batch_Record, Message: This entry already exists in batch X when calling nSetKey with parameters

Occasionally when syncing invoices from Quadient AP into Sage 100, you may receive the sync error message 'Code CI_Batch_Record, Message: This entry already exists in batch X. when calling nSetKey with parameters'

How to resolve this sync error

This error occurs when an invoice with the same invoice number, vendor, and total as the invoice you're trying to export has already been exported in Sage 100 but is not yet posted. Locate and post the invoice in Sage 100. You can then mark the invoice as exported in Quadient AP using the steps here. If the invoice is a duplicate, use the steps here to delete the invoice from Quadient AP. 

If you cannot find the unposted invoice in Sage 100, you may be experiencing a 'ghost' batch. This is where the invoice batch successfully reached Sage 100, but the batch can not be located. In this case, please reach out to Sage 100 support for further assistance. The Quadient AP Support team is unable to resolve the 'ghost' batch issue.
