There’s no direct way to undo a depreciation run. Here are a few suggestions on getting back to the prior calculations:

 

In Sage Fixed Assets - Depreciation:

• Run Depreciation to the correct date. The program is designed to run depreciation to any given date into the past and the future. You can an incorrect depreciation run by rerunning the depreciation twice. First, run depreciation for the period before the desired period, and then for the desired period. See Depreciation this run is too high for more information
• For example: You need depreciation through 12/2025, but run it for 06/2025 instead. To get to 01/2025 depreciation numbers, run depreciation back to 12/2025 and then to 01/2025
  Or:
• If there’s a recent backup of the database: Restore from backup. Do this with caution, as it will erase any work you did before making the backup
