Hi customcafe-acc-g,
As you have previously recorded the bills as paid once downloading the ABA file, you need to undo these Bill Payments so you can create a new valid ABA file.
- Go to the Expenses menu, then filter to Bill Payments and any relevant date range/payee as required.
- Select the bill payments and under the Batch Actions tab, select Reverse bill payments.
- Go to the +New button, select Pay bills and recreate your batch payment and download the new ABA file.
