Issue with Depreciation Posting

HI,

I have one doubt regarding Depreciation Posting. I have created couple of Assets and run the Depreciation successfully till the last posting period. Now, I have created another new Asset (Acquisition date is 01.04.2011), for which I want to run Depreciation now for the previous periods. As I have already run Depreciation for the previous periods, How can I run for this new Asset?

Pls let me know the settings to be done in AFAB.

Thanks
