What is Best practice for additional investment in existing FAM Asset? I see revaluation, write-down … yes, I know it could be negative and that lead to increase Current Asset Value, but …. it is still “fake” writedown

revaluation is usually for intact assets, that is when asset’s value changes without your interaction with it. if you adding more to your asset you can record it as a separate asset (labor or material) and add them as sub-assets to your main asset
