The requirement is as follows,
I made an asset purchase in the year 2014. That time the asset value was 1000. The useful life of asset is 5 years.
In 2015 I made an addition to the asset with a value of 1200. Now my asset value for the year 2015 is 1000 + 1200 = 2200. The depreciation for the same year is calculated with additional value.
Now the client is expecting the depreciation to be distributed equally for the remaining years which is not happening currently.
