Depreciation run issue.......

Hi,

I am trying to re run the depreication as it calulated wrongly for last 2 months. Now when i am executing it through AFAB T.code, it is giving me an error that posting period is not open for period 1. Our fiscal year start in Oct and ends in Sept. I checked the OB52 settings and there it is shoiwng that currently period 3 is open.

So is there any other way through which i can re run the depreciation posted. I don't think business will agree to open the closed period.

Please suggest.

Regards....
