Tech Support is absolutely no help in resolving this issue.

It's just a simple change to the field lengths in the ASCII file layout.  We were able to determine the change and make a fix to our ASCII files so they work properly.

We were contacted by our users of Quick Trial Balance that they were having problems with our ASCII export for Proseries.  We contacted Proseries support and discussed with the technician what the problem was and they were completely clueless.  It looks like this change may have been made in the 2021 version but it may have been after the filing season so you may not have run into it.

We had it fixed the day it was reported to us but not because of any information Proseries provided to us.

If you're using the dBase import option, you may be out of luck because ATB was the one that used that file format and it is no longer supported.  Not sure about any other trial balance software.
