Segregration of depreciation adjustment by event and source type

Summary:

Hello, we have custom reports where we can see the difference in cost and depreciation between 2 asset books for each event as well as the beginning balance difference + event/source type differences = ending balance difference.

Now, for some countries like France or UK we may perform revaluation in the corporate book, for others like Eastern Europe, revaluation is performed in the local tax books. We also have Impairment which is performed in many countries.

So we want to add columns for Revaluation and Impairment to these reports in addition to Additions, Adjustments, Retirements, Reclassifications etc.

For the cost report we are good as I have analyzed the FA tables from the Asset Trace files but for depreciation, I want to understand if we can segregate the depreciation adjustment amounts to 1. what was the depreciation amount before an adjustment such as Impairment, revaluation and 2. what is the depreciation after these adjustments.
