I have two XML data set. And I am trying to build master-detail relation.
For one of the data set I created beforeOpen script

this.queryText = "/report-data/content/group/group/SUBREPORT[@ORD_SYSID=';"+ this.getInputParameterValue("param_1")+"']";

where param_1 ? input parameter for Data Set
But I am getting an error :

Hi Arseniy,

You're trying to create a master and detail within one report? Can you explain a little more about what you're trying to do? Are you just trying to create a grouped report? Is this something you could possibly do with an embedded table and filters? Maybe I should just wait for the explanation!
