how to reduce the excess posted depreciation to an asset? i mean to say reverse the depreciation.

What is the exact requirement

1. Correct a wrong depreciation run caused by wrong parameters (wrong depreciation key for example)
2. Reverse a future depreciation run executed by mistake

Hi 

You can't reverse the depreciation. You have to change deprecation key and repost deprecation. New posted deprecation will increase/decrease the previously posted deprecation.

Yes agreed depreciation run reversal is not allowed in SAP, only depreciation key can be changed.
