BDC is not working properly- T.Code: AS91

Hi Gurus,

I have done bdc recording for T.Code : AS91.

But when i navigate to the depreciation Tab, the depreciation date by default is the 01 date of that month. But when i change that to the capitalization date ( eg: 15/10/2007 ) as per customer requirement it is givin me a warning message which is intterrupting the bdc, as a result the upload is failing.
