How to achieve this scenario ?

Hi Experts,

My requirement is to run depreciation on declining balance method, have salvage value of the cost and the depreciation should run on cost and not on recoverable cost

Original Cost : 56000
SV : 5% or 2800
Recoverable Cost : 53200

Depreciation for the month of May- as per system : taken on recoverable cost ; 53200*13.91%/365*31 = 628.50

As required ; Should be on Cost : 56000*13.91%/365*31 = 661.59

and at the end when it reaches the Salvage value the depreciation should stop running.

Thanks

Sachin
