Query Perfomance Issue

Hi gurus,

We created a query on an InfoProvider, it tooks about 20/30 minutes to execute and returned the query results, does anyone have any inputs/suggestions?

We are using the New Reporting Tools of BI NW version 7.0.

I'm also using tcode RSRT to research the performance issue.

Thanks in advance for any helps/inputs, the maximum points will be rewarded!

Kind regards,

Niki
