Can we create the hierarchy for test plan?

Can we create the hierarchy for test plan?

Such as we have an overall test plan for the release, and have several sub test plans link to the overall test plan.

There appears to be no way to have parent test plans spawn or reference child test plans.

I have been told to use custom categories and placing our own values in these categories. You may be able to accomplish what you need by doing the same thing. Create one category called "Release", then another with your sub-category. Every test plan would have the same "Release" value, but would have different sub-category values.

Using a view builder you can then filter things down by these category values to see the logical hierarchy it creates.

Thank you very much for your reply.

I tried your solution. It could be a workaround for now.

In future, hope RQM can provide this function.
