Reporting Error

I have a customized report done in BIDS. There's no problem in BIDS but when I added it in CRM there's an error "The report cannot be displayed. (rsProcessingAborted).

I've done these steps:

I also do the setspn -a http/..........

still no luck in viewing the report.

any advise on this?

Thanks in advance
