Stop user from triggering incompatible transitions
Users can be stopped from triggering two incompatible transitions in a workflow. For example, A user should not be able to Close an issue Resolved by him. Similarly, a user should not be able to Approve a task Developed by him. For such customized scenarios, you can set the Separation of duties condition, on the transition which the user should not be able to trigger, once he has transitioned between two selected statuses. This condition can hence also be used as a security check.
