RE: Fixed Asset Acquisition Reversal
Use the Cancel option for correcting FA entries. Reversing will just cause more problems in future.
Filter and select the needed entries (can be one or several selected), press Cancel button. Entries will be created in FA journal (or FA G/L journal based on setup). Then just post the Journal lines.
Canceled entries will not show in FA Ledger entries and are moved to FA Error Ledger Entries - so You don't see them in daily use afterwards when checking the history or FA entries.
