I needed to make some changes to the ABA file, so after I marked the Txns that were not to be included as error, I pressed the Extract button, but the new file was blank. Where are the other Txns?
The first time a Batch is extracted, it will update all Txns to the status Direct Debit Processing. Txns that have Direct Debit Processing therefore be added to subsiquent ABA files that are extracted. Only Txns with the status Direct Debit Assigned to Batch are available.
Update the Txns to be included as Direct Debit Assigned to Batch and then extract again.
