If you have submitted revisions and refreshed your data within the same day the refresh process will update your reports with revised data. If more errors are found later revisions can be reported using HEPCAT and you will need to refresh your verification reports again. You can continue working through the refresh and verify process as many times as you need until you are confident with the final numbers in your reports. When your satisfied that your reports accurately reflect the data in your own student system they can be signed off.
