Hello.
Last time I heard about this problem, the problem went away after the number of GRC rules used for the check was lowered from all their millions of rules to the most important ones that pose a real risk. There are companies where it is not possible to do anything about it, because they're too small. And these companies are still in business. Even if you clear the conflicts on the role level, you can land with the same problem on the user assignment level.
Can you maybe elaborate on these conflicts? How serious are they? How many roles and users are / can be affected? What is the module / area that it is touching?
Cheers Otto
