The Change Management - Change Model Foundation Data plugin (com.snc.change_management.change_model.foundation) includes state field policies for the base system change models. All default policies make fields mandatory
only.
To view, edit, or deactivate these policies, go to the State Field Policies related list on the model state record. To add or modify policies, see [Add state field policies to a change model state](https://www.servicenow.com/docs/xd4vqT4o3_iEV~uxhbXFyA "Make change request fields mandatory or read-only in a specific state of a change model by adding state field policies to the model state.").
