In SSRS, I have a report that is contained within a List Item. The report is looped for each student that is selected. The theory is for a principal to select his school and grade level, to create the report for all students within the grade. This works fine within BIDS.
The report generates fine for grade levels with lower enrollment. I have had success running this within SSRS for 10th, 11th and 12th grades (all with enrollment under 900 students for the school). When i run the report for 9th graders (967 students) or any combination of the grades that run successfully alone, the report doesn't generate.
This is not a timeout issue, since i have tried setting the timeout to 10 minutes. The "Loading" icon shows for about 1 or 2 seconds and then disappears, returning a blank screen.
Any limitations as to how many rows a list item can return? Any help would be appreciated. I can't seem to figure out why SSRS is not returning this report.
