Webi Ranking

Hi Experts,

I have a report where it has to display Date, Region, Store, Store Phone no, Dialled Phone no, and No of times called. I want to restrict this to the TOP 50 records based on the No of times called. I have applied ranking on No of times called but it is displaying more than 50 records, how to restrict the report to the 50 records only based on No of times called. Please help me I cannot proceed further until this is resolved.

Appreciated in Advance....

Regards,

C
