Hi, 

If you want to use the value of the main report query in the subquery you need to , map those fields to pass on to the parameters in the subreport and when the query runs it will automatically send the values to the subreport and there would be no need to run it twice. In a single go job will be done. 

For mapping the values to the subreport- 

1. First create the dummy parameters in the subreport which would recieve the values from the main report .

2. Click on the subreport element in the main report.

3. Then you need to set the connection as Use a connection Expression

4. Then you need to set the expression to $P{REPORT_CONNECTION}

5. Then you need to add the parameter 

Have explained the above in a jpg file. refer to it for more clearification

I hope this helps to resolve your query.
