Dep. Run does not affect the asset!!!

Hi experts;

     I wanted to make a Der. Run. for an asset in a closed Fiscal Year 2012. So I changed the closed Fiscal Year on OAAQ to set it for 2011 and opened the period on OB52 to allow posting in such year (2012).

     And then went to AFAB to run depreciation on the required asset, there was no error message but there is a WARRNING message ((No Document was created in this run)) however the TEST RUN completed successfully.

So, can anybody kindly advice and help thanks;

Thanks in advance;

Kind regards;
