Execution results of multiple scripts in one report ?

Which report are you referring? If you are just talking about the execution result seen in the RQM UI then there should be a Test Suite Execution Result, that contains an overall status for the test suite and links to all of the individual test case results. To see this use the main RQM menu items and go to "Execution->View Test Suite Results". Then click on the link associated with the test suite of interest.

I'm referring to the execution report. As you state, you can see the results in the Test Suite Execution Result, but you have to drill down into every single test Script Result report for the details. I would like a detailed report for multiple scripts in one, not a report per script
