Dear Jyostna,
You must have created a new depreciation key to depreciate the asset daily basis.
Standard behaviour:
If depreciation key is changed for previously depreciated asset, system will calculate the difference of already posted item and it will adjust the same in the next period.
In your case the asset was depreciated till 12- 2014 on a monthly basis, but now you have changed the dep key to calculate daily basis, hence already posted data is recalculated in a daily basis and adjust in 2015, you can see a adjustment entry of 23877 being posted in 2015.
Now the depreciation will be calculated from the net book value 24070 for the remaining useful life 5years and 7months i.e., 4303.
so for the next five years the value is 4303.
but for 2020 it will calculate only for seven months so the value is 2523, the asset still has some value to it.
Actual issue: ( let me know what is you requirement).
1. you don't want system to adjust the Book value based on already posted dep?
2. You need the book value to become zero at the end of useful life?
Based on the requirement I will suggest you the solution.
