Hi, I have reports to be migrated from actuate to jasper. To my knowledge it has to be implemented in jasper using subreports concept. I have also done adding 2 sub reports in a new report detail section but while previewing i do not see the output however if individually run i can see the output. do i need to add any parameter or to set any connection path? What all settings need to be done to link 2 reports. Please help me out. Thanks.
