can anyone help with this question?

From Carolyn Pampino: If you use RTC plan-items to represent your 'requirements' as many agile teams do, the approach is to link test cases to the plan level items in RTC -- as shown in the blog (http://jazz.net/blog/index.php/2009/08/26/sprint-alignment-for-developers-and-testers/). There's no need for additional links to 'requirements' in this case - you can remove the 'Requirements' section from your Test Plan and Test Case TOC - by managing the sections.

If you have requirements somewhere else, such as in RequisitePro, or Requirements Composer, you establish a link between RQM & the Requirements Management system. Then you can import the requirements. If this is the case, the RQM user documentation explains how to do this.

Note: To link a TC in RQM to a Story in RTC the "Plan Items" section needs to be available within the TC. "Plan Items" section is not a default section in the default Test Case template. You might need to create a new TC template that includes this section (via Manage Templates) or use the Collaborative ALM Test case template which has it pre-loaded.
