Talk:Compare tool doesn't recognize changes
From Axaptapedia
This bug was fixed in Axapta 3.0 sp3:
GB-249-622-DEBN Import/Export problem in Axapta 2.5 and 3.0. Previously, if you changed a field property on a form, then exported it, and then imported it again, the change would be ignored, despite being preserved in the export file. The problem would only occur if no method existed on that particular field. The error has been corrected.
