When I do exactly what you said, I get the Planning report for all of the test cases in that folder.
There are tests in that subject folder.
I do have privileges to run reports.
When I select the report called "Subject Tree Report" I get nothing. No test cases at all.
In addition to this, no matter what the steps are leading up to that selection, the subject folder that it appears to be reporting on is not the one I have selected or wanted. However that folder does contain test cases....but even these are not on the report.
I assume you are selecting the "Subject Tree Report" from the "Analysis" object at the top of the Test Plan screen. Mine gives a report of all folders. Unless you use the "Report Selected" it defaults to the entire tree. But if you get nothing, then yours is BROKE!
Success is the ability to go from one failure to another with no loss of enthusiasm.
