HP ALM 11.0 | Requirement Traceability | Requirement to Requirement mapping

Hi ,

In my project i have got 3 kinds of requirements (Functional,Business and Usecase).

I consider functional requirement as the parent one and mapped both business and usecase requirements to it using Trace-From and Trace-To.

Once the above steps are done and when i mapped whole set of testcases to Functional requirements, direct cover status of Functional requirements is shown as "No Run".

But still, Direct Cover status for both the business and usecase are shown as "Not Covered" only.

Please assist me how to fetch the coverage of all traced requirements?

Thanks,
Shankar
