Regarding RQM 3.0 exporting of test cases into CSV
Accepted answer
Chandrahasa,
There it no built in way to export a specific Test case in version 3.x to a CSV file
You could use the REST API (https://jazz.net/wiki/bin/view/Main/RqmApi) to assess the and export the data to XML
In version 4.x you can export the list of Test Cases from the Browse Test Case view
