Recognizing that many of my clients have been using nv1 since 1987, and we’ve never purged any data, they possibly have 25,000 or more bank items reconciled using codes such as: 990101 to 2050930.

Or is it possible to just change “One” old entry to “20509-01-01” so it will pick up the new code? I’m not in the books, but by changing an old will it change the position of that entry and therefore not accept it as the starting code?
