Triple shift dep value is not calculating correctly

Hi experts,

I have a problem in triple shift depreciation calculation where it is not calculating correctly.

According to client the Dep should be calculated on the basis of rem useful life.

Suppose Net Book Value is Rs. 100 on 01.04.2015

Rem useful life is 10 year

So for the fiscal year 2015 the dep amount should be

Now the wdv =100-25=75

Dep for next fiscal year should be

But system is showing the Rs 25 dep for fiscal year 2016

I have configure the dep key as below

Depreciation Key Config:

I Made in below changes in the asset master:

and the asset register is not showing the correct dep value for fiscal year 2016
