Asset Ordinary Depreciation start Date

Dear Gurus,

One of my asset is having Asset capitalisation date 31.05.2010 and ordinary start depreciation date (in depreciation tab) is 01.03.2010.

I need the depreciation to be calculated from 01.03.2010, but the system calculates the depreciation from asset capitalisation date ie., 31.05.2010

Where should I go and change so that my system should calculate the depreciation from 01.03.2010

Regards,

Babjee
