Depreciation proposals in AX 2009

Hi all,

Am facing problem with the depreciation i dont know how i can find a solution for it.

I just start worked with new company dealing with Ax-2009, but unfortunately they made the depreciation manually each month since they started, so we have a lot of data should be make this time & all the past years should be done also, so i try to make a proposals depreciation but the date coming with the old dates & i cant change the dates for all lines manually because its more than 28K lines, So if there is any way that help me to fix this big false please contact me ASAP.

please contact me even if you want open my PC for you to see the false by yourself.

Regards,

Saleh Ali
