How to fix depreciation calculation ?

Hi,

I am tried running depreciation for April in proof mode for company however the deprecation calculation doesn't agree to our Sun system.

Asset balances for cost and accumulated depreciation agree as of the end of March however depreciation is usually about 44k a month.

I had a look at some individual assets and it looks like the system is calculating an adjustment for some assets that are fully depreciation.

how to fix that ?

Acquisition Date  01/05/2005

Depreciation Ended 02/05/2005

but the depreciation still 172.15, it supposed to be 2,065.78

Thanks
