AFAB - Depreciation Run

Hi Gurus,

We are implementing assets and we used t-code AS91 put in all the assets values for the year 2008 i.e. accum. dep for 2008 & aquisition value.

When I am running AFAB to post depreciation for 2009 I am getting a message :the are no area's to post in company code XXXX:

Message number AA 690.

Can someone help ??? It seems like something is missing in customizing but I am not sure where??

Thanks

Best Regards,

N
