Hi Junior,
There is no standard way to reverse a depreciation run in Asset Accounting.
For further information on this topic, please refer to the following
blog:

As it says in this blog, there are different options to correct
values on an asset. I think the most commonly used one are in fact
a write-up or unplanned depreciation posting.
Hope this helps
regards
Ray
