Parameter passing from sub to master report ?

2004-04-15 05:23

Does Jasper support passing of parameter values from a subreport to the master report?

 

I have the totals of few fields retrieved from the same set of tables in two subreports (where clause is different in both the cases). I need the net difference of these fields in the master report.

 

The report requirement is as as follows:

 

SubReport 1

**************

Sub1Total1 Sub1Total2

 

SubReport 2

**************

Sub2Total1 Sub2Total2

 

Main / Master Report

************************

(Sub1Total1-Sub2Total1) (Sub1Total2-Sub2Total2)

 

Is the above output achievable in Jasper?

 

Any help would be highly appreciated.

 

Thanks & regards

Aneesh

If you send the parameterMap of the master in to the subreport, then the subreport could add its total to the map. Then when the subreport ends, the master will still have a reference to the value.
