Plugin Description
Change Management - Core\[com.snc.change\_management\] Change management is used to create and manage change requests. Once this is activated, the values for the **Type** field on the change request are updated.
**Warning:** Activate the Change Management - StateModel plugin `(com.snc.change-management.state_model)` only on an instance where the Change Management - Core plugin `(com.snc.change_management)` is not yet active. State Model activates Core automatically. If you activate Core independently before activating State Model, State Model does not function as expected. ## Procedure 1.
