Pass parameters to sub reports

[Ettya]

I have created a report that calls three sub-reports.

Each sub report resides inside a report group.

There is one parameter that is defined in each of the Sub Reports and in the calling report.

I assumed that the value of this parameter will be sent to each of the sub-reports but it doesn’t seem to happen (when I run the main report, the sub reports are empty with no data).

Is there anything I should do in order to make sure that the parameter will be passed to the sub-reports??

You need to establish a link between the parameter in the main report and the parameter in the sub-report.

 

 

To do this you edit the subreport's properties in the main report and set up the parameter settings under the Subreport Parameters tab.

If I have a parameter called "X" both in main and in Sub report and I want the sub-report parameter to get teh same value set to the main report parameter.

Is all I need to do is just add a line where

Parameter = X and Expression = $P{X} ??

 

Thank you,

That's all you should need to do.
