You can transition based on all but one specified value. You can use Other Results when multiple transitions exit a single step. Other Results acts as the transition if none of the other explicit transition conditions are satisfied.
For example, you might want to transition all Critical requests one way and all other results (High, Normal, Low) in a different way.
To add a transition based on all but one specific value, create a transition from a workflow step based on a value in Specific Results. Create a second transition from the same workflow step. For the second transition, specify Other Results in the Define Transition window.
