How to achieve multilevel(Plan-Case-Script) report for RQM in RPE?

Hi

I'm using the Tutorial about "RQM Multi Level Report Tutorial" found on the wiki. The report list the test scripts for each test case in the test plan (3 levels)

It says that I should have in my report 4 data sources :

-TestPlan_feed

-TestCase_Details

-TestCase_Feed

-TestScript_Details

I have configure the TestPlan_feed manually on the .dsx and the TestCase_Details dynamically using the "Data Source Configuration" box on the report (as the tutorial says so).

I have achieve to list the test cases in the test plan. But I dont know how to configure the TestCase_Feed. Should I configure the  TestCase_Feed manually also in the .dsx? If I do that it list all the test cases not only the one from the test plan. Or should I do it dynamically? Can some one help me please. I dont understand that important point on the Tutorial

This is the link to the tutorial I'm using https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/Rational%20Publishing%20Engine/page/Tutorials%20from%20the%20old%20RPE%20wiki

Is the number 11. I'm stuck on Stage 4, dont know how to configure the TestCase_feed some help please!
