Custom Report not working in CRM 2011(RsProcessing aborted)

Hi Gurus,

I have created a custom report via Visual Studion 2008(BIDS) , it is working fine when viewing the preview . once i imported into CRM 2011 . it is showing  the i/p parameter screen ,once i click the view report button , after some time it is throwing out an error "Report cannot be displayed
RsProcessing aborted" .

I have tried re-starting the Reporting services configuration manager  found as solution in internet and did couple of tricks as well.

Unfortunately bad luck :(

Please any one give me a suggestion .

My custom report is built on top of a Stored procedure .

Thanks in Advance .

Thanks,

SS
