whats your understanding of "link" these tests? you can arrange the scripts within one testset (in the Test Lab), but its not possible to call a manual test from within a automated test... (as example)
Do it this way:
- Connect to QC from QTP.
- Open Automation Script and save it to QC.
- Open QC and in Test plan module go to the node where Automation script was saved.
- In Design Steps add manual steps.
