How to change the query for subreport in crystal report?

Question

Hi all,

I display a main report with 2 subreports. I passed a parameter to the subreport. I filled the subreport from different table. Sometimes, I am getting more than 2 records. But, when I pass a parameter to the subreport, that report should display only the first 2 records from database table. So, I need to change modify the query.

Where should I modify the query for display only 2 reocrds in subreport?

Thanks
