I would like someone to tell me whats happening in this scenario. I have a report that works well when viewing the report in normal Report builder 3.0. The report has some parameters with default values. Now I try to view the same report using the report manager but the report will not run. I can't really figure out whats causing the problem. Once I try to view the report in the Report manager, the report will behave as if it is about to run and then kind of stop again without showing me any value. Does it mean there's a limit to what can run using url.
