Note: Exercise caution whenever deleting a Number Format as this will remove the code from the system and prevent users from accessing the value or corresponding data in the future. Deleting a Number Format will result in any location in a Line, Column or Report Definition which uses that format to be reset to a general format. If a Number Format is no longer required for any reason, you may want to consider making the value “Inactive” instead, using the Inactive checkbox in the Number Format worksheet.
