It would be very helpful if we had the capability to change the date in Treasury when generating an ACH transmission file. If we generate the file too late in the day, our bank rejects it due to the date. Was told by support that you can only change this after the file is generated.
If you upload yrou EFTs manually to yoru bank and save the NACHA file after it is generated, you can open it in Notepad and edit as needed. Depending on your bank's options, you may also be able to change the date during upload to your bank.
