Hi Colleen,

In the most recent service pack for BankRec 9.2A (June 30, 2015), an issue was identified and resolved related to the NSF process and attempting to NSF multiple customer receipts with the same document number. This used to create duplicate NSF transactions in the BankRec batch, but no longer does. This is the text from the Release notes and the ReadMe

If the ‘Check for duplicates’ option is enabled, when multiple NSF transactions are to be created where the same check number is used on separate receipts, there is now a warning that there is a duplicate Reference that must be corrected before generating the NSF batch.

Could this be the problem you are running into (and the solution)?
