BIRT Report Drill Through Issue

I have a custom BIRT report in RTC that works well. I want to add drill through on certain data field in the report. I changed the Hyperlink of the data field to point to another BIRT report (this report also works). It worked well in my Eclipse client in the "Report Design" perspective. I then deployed the two reports to the RTC server, and ran the report from a web browser. However, when I click on the hyperlink, it opens a new window and shows the following error message:
------------------------------------
The project run does not exist or is not accessible with your credentials.

If you have JazzAdmins privileges you can investigate the problem in the Jazz Admin Web UI.
-------------------------------------

I am a Jazz Admin so I should have all the privilege. I deployed the two report templates under "Report Templates" in RTC server, and created the reports under "Shared Reports".

I am running RTC 3.0.1.1 and BIRT 2.5.2.

Can anyone help on this?

Thanks.
