Additional depreciation on India Block of Assets

HI All,

We are facing problem regarding depreciation calculation at the time of data migration.

My client is using financial year WDV depreciation method. In this system calculates depreciation for each finacial year on the opening WDV of 1-Apr. For Example-

Purchase asset "A" on 1-Apr-2012 of Rs. 100000 & depreciation rate is 12%p.a. Now depreciation for FY 2012-13 is 12000 rs. i.e 1000 rs per month.

Now on 1-Apr-2013 WDV value is 100000 - 12000 = 88000. Depreciation for FY 2013-14 will calculate on Rs.88000 only. System is calculating this properly.

We are migrating the data from clients legacy system to oracle R12. We migrate asset cost as well as its accumulated depreciation i.e. Rs. 100000 & Rs. 12000 for FY 2012-13.
