WebIntelligence - Refresh taking huge time

Hi Team,

I have an issue in BI launchpad. Created WEBI report using BEx as a source and enabled Refresh on open option too. The issue is when the user open the report, its taking lot of time for displaying the prompt screen(Approx 30 mins). And we have only one variable for prompt.

But when I used to create the same report in Advance analysis for OLAP, its running fast in BI Launchpad.

Is there any option to resolve this issue?. Please do the needful.

Awaiting for the reply,

Thanks in Advance..

Krishna.
