Accelerated depreciation Partial NBV

Dear Friends,

Accelerated depreciation

1.      1  Full NBV should be Zero

2.      2  Partial NBV should be depreciated, remaining NBV should depreciate remaining life of asset

The frist scenario

Ex: Asset acquisition value         348,914.00 on  01-01-2009

Asset life                                   10years

Depreciation on 31.12.2012        139,565.60

NBV is                                      209,348.40

I have to do Accelerated depreciation Full NBV should be Zero I had created one new depreciation Key to make NBV Zero. And assigned in Asset master new depreciation Key and did depreciation run NBV become Zero.

The second scenario

Ex: Asset acquisition value         348,914.00 on 01-01-2009

Asset life                                   10years

Depreciation on 31.12.2012        139,565.60

NBV is                                      209,348.40

I have to do Accelerated depreciation partially for value 190,000.00 remaining 19,348.40 should be NBV on this depreciation should calculate for the remaining years.

Pls suggest what needs to be done.
