Query regarding subreports

[deepathakur]

Hi,
when i linked the subrport with main report parameters it doesnt show any output, when I remove the links for parameter fileds, it shows the data.
I have included 2 groups in my subreport, the data which should get fetched (means the groups) is indepedent of parameters which i have linked with main report.
can any body tell me why this is happening?

There could be multiple reasons,
1, Might be there are inner joins between the tables.
2, There is no data for the parameter
3, Check is the sent parameter is matched with any table's column which leads to record selection.
