Configure the Change Models properties to access the Change models capabilities when
creating a Change request.
The following properties enable you to access the Change Models features. For upgrade users, these properties are set to true.  
Important:  
A wildcard search for <kbd class="ph userinput">*change_model</kbd> in <kbd class="ph userinput">sys_properties.list</kbd> may return additional properties depending on the installed plugins, such as `com.snc.change_management.change_model.default_read_roles`, which controls read access to change model records. Confirm the value of any role-based property before changing it. For the roles referenced, see [Components installed with ITSM Roles - Change Management](https://www.servicenow.com/docs/lzl1cW8mOtAt6Yx8UjgcPg "Several user roles are installed with the activation of the ITSM Roles — Change Management plugin (com.snc.itsm.roles.change_management). Security ACLs to support the security model for Change Management and related functionality are also installed.").  
Enter <kbd class="ph userinput">sys_properties.list</kbd> in the navigation filter and enter <kbd class="ph userinput">*change_model</kbd> in the Search panel to view and edit the properties.{#change-models-properties__table_szt_rh5_znb__entry__2}

| Property | Description |
|-|-|
| com.snc.change_management.change_model.hide | Hides the Change models feature when the com.snc.change_management.change_model.type_compatibility property is enabled. When creating a new change, you do not have the option to choose a model, and the Model field is not available on the Change request form. |
| com.snc.change_management.change_model.manage_workflow | Enables Workflow management support for ChangeRequest API if the com.snc.change_management.state_model plugin is installed. This will call the 'deleteDefaultWorkflowContext' method to be called on specific state and type changes. |
| com.snc.change_management.change_model.type_compatibility | Determine what kind of change requests (type or model-based) are created. Enables Change Type Compatibility for Change models if the com.snc.change_management.state_model plugin is installed. When set to true, the property allows changes to be created with both the type based workflow and Change models. Note: The default value of this property is False. When set to false, change request will be created only using change model. |
| com.snc.change_management.change_model.default_read_roles | Comma-separated roles that have read access to change model records. Use this property to restrict who can view change model definitions. |

Note:  
If type compatibility is set to false, and change type does not match with a corresponding change model, the change model is marked as Legacy.
