Hi,
I've created a custom export scenario for BNZ Bank in New Zealand and mapped it to the payment method NZBNZDD. This setup is configured for exporting batch payment files from the AR module for direct debit processing.
The setup appears to be correct, but for some reason, I'm encountering the following error:
"An error occurred while trying to retrieve 'Unique' part from specified."
I'm unable to identify the cause of this issue.

Does anyone have any insights? I've attached the export scenario and error log(SQL Profiler) for reference.
