Description
Business rule executing before or after update/insert on sys_user_has_role triggering frequently even though it appears no new inserts or updates have occurred on this table
Release or Environment
Subscription Management plugin
Cause
The Subscription Management plugin installs a scheduled job that runs every 4 hours that is meant for Usage Analytics. This performs a test run where it creates a user called 'licensing.role.testing'. This user will receive an assignment of a few roles which is why the business rule on sys_user_has_role is triggered. The job is located here:
https://<instance-name>.service-now.com/nav_to.do?uri=sys_trigger.do?sys_id=87ed51531f2121006d691b220e8b70bd
Upon completion, both the user and the associated sys_user_has_role records are deleted from the tables but can still be found under the Deleted Records module in your navigation pane. In the deleted records, look for the payload containing the user name licensing.role.testing string and you will find all the deleted records for that day related to the scheduled job.
Resolution
If you want to avoid your business rules from giving you what appears to be a false trigger then add a condition to your business rule to avoid executing it when the associated user is named 'licensing.role.testing'
