Hello Pankaj,
It is not possible to change from a depreciation key with Depreciation to the day to Monthly depreciation or the other way around.
In the asset master record, the first time you post to a fixed asset,
the system updates the number of periods to be taken into account in the
depreciation calculation for this fixed asset.
Therefore, in a fiscal year with 12 periods, the number of periods is
always 12 unless you use half months or depreciation to the day. If you
use half months, the number of periods is 24. If you use depreciation to
the day, the number of periods is 365.
If the depreciation start date is in a closed fiscal year, the system
must no longer change the number of periods in the asset master record
because the depreciation in the closed fiscal year was calculated on the
basis of this number of periods and must no longer be changed.
If you wish to depreciate as of a certain time considering depreciation
to the day, we recommend to transfer the asset to a new asset using
depreciation to the day. This is the only proper solution.
I hope this helps to clarify the system behaviour,
regards
Ray
