OTBI Report Too Slow / Not Generating Results

Summary:

Have created a report to pull all roles for all users (Audit purposes), and admittedly there is an excessive amount of data to pull. That being said, when running the report, i leave it running for 2-3 hours and nothing generates, the loading icon just runs. Even when scheduling the report, nothing generates.

Is there anything that can be done to fix this?

Thanks!
