Where can a change manager define the conditions that must be met before a change request can move from one state to another?

State choices define the available state values in the choice list but do not specify conditions that must be met before a transition is allowed.

State conditions is not a standard ServiceNow Change Management configuration object for defining transition prerequisites.

Model State Transition Conditions are configured directly on the change model and specify field values, approval states, or other conditions that must be met for a transition to be permitted. This provides granular, model-specific control over state progressions rather than applying global rules, making it the correct location for defining pre-transition requirements.

Dictionary Overrides allow table-level field attribute changes but are not used to define state transition logic or conditions on change models.
