Print when there's data on the sub-report

[siyabonga.bushula]

Hi I have a Jasper report with a sub report now I want the report to display the data only if there's data on the sub-report hence the details are from the sub-report only headers from the main
I created a variable which is a 1 or 0, when this variable is 1 it means there's a data to display so I set the print when to " $V{Variable_1}.equals(1) " and it comes with a blank report I would appreciate if someone could help

I can't see the jrxml file, so I'm guessing.
It is possible that the calculation timing of 'Variable_1' and the comparison timing are out of sync.
Changing the 'ResetType' of 'Variable_1' may help.

If your requirement is not to display the group header itself when there is no data, then you can control it more easily.
Set 'Print When Exception' to '$V{COLUMN_COUNT} > 0'.

My last reply was wrong.
This did not fulfill your requirement.
I'm very sorry.

And after that, I tried many things by trial and error.
But unfortunately I could not get 'v_check' properly.
Sorry for not being able to help you.
