The Sage Fixed Assets database only contains one set of depreciation information at any given time. You can't reverse depreciation; only run depreciation to a different date. The program is designed to run depreciation to any given date into the past and the future and reproduce consistent reports. This assumes you've changed no the assets.

In Sage Fixed Assets Depreciation

1. Calculate depreciation to the period before the desired period (Depreciation, Depreciate).
   • Skip this step if you don't need Depreciation This Run amounts or a General Ledger Posting report.
      NOTE: This run of depreciation is to set the Prior Thru date for the assets. Don’t attempt to tie this report to old reports.  
2. Calculate depreciation for the desired period.
3. Run any additional reports needed for that period.
4. Run depreciation back to the current period (repeat Step 1 and 2 backup current period) when finished.

Considerations and drawbacks

• Disposed and transferred items will show as they were when you previously ran depreciation to the data.
• Partial disposals and partial transfers won’t appear the same.
• The total amount of depreciation will still be the same.
• Deleted Assets will remain deleted and will NOT appear on the report.
• Assets don’t appear when their Beginning Date or Period Close Date comes after the depreciation run date.
• There can be rounding differences when rerunning for past periods, or rerunning back to the current period.
• If you recently turned on adjustments, the adjustments will show in the prior period.

For Prior year reporting, an alternative is to keep a Year End copy of the company. See Year End Close.
