Prevent Accumulated Depreciation and YTD Depreciation to be recalculated for a migrated asset

Hi,

I've to load migrated assets, with its current Accumulated Depreciation and YTD Depreciation values. I've loaded the Assets, using Web ADI, with the Accumulated Depreciation and YTD Depreciation values along with Amortization flag set to 'Yes' and Amortization Start date in the current period. As soon as I run the Depreciation for the month, Accumulated Depreciation and YTD Depreciation values gets recalculated, which I want to prevent. The asset should be retaining these values and the periodic depreciation should be from this point.

Thanks for your help.

Amar
