Depreciation area does not appear in the asset master data however it is set in the Asset class. If other asset is created in the same Asset class that depreciation area is automatically set in the asset master (it proofs that it is not a problem with Asset class).
I tried to set that deprecition area directly in the asset master data but all the fields are blocked for changing (is it possible to change that?).
What should I do as I need to post on that area ?
