Detailed Addition of FA Item

Hi

    I am  adding an Asset through Detailed Addition and there by specifying Accumulated Depreciation and YTD Depreciation (Apr2008-Mar09). After this when i run Depreciation to close the period again Depreciation is getting calculated for Mar-09 with change in YTD.

   Please suggest what changes should i make so that YTD depreciation will be constant without addition of Depreciation for Mar-09 and it should calculate as usually from Apr-09.

Thanks
