Is this a benefit of using the Run Rule feature of the Debug-Object page?

The statement isfalse. The "Run Rule" feature on the Debug-Object page is not intended for creating, modifying, or deleting SailPoint database objects. Instead, it is used to execute specific rules for testing and debugging purposes. While it allows you to test the logic of a rule by running it in isolation, it does not directly manipulate database objects. For creating, modifying, or deleting database objects, administrators would typically use the appropriate IdentityIQ APIs or database scripts.
