Key Features

Include Affected Configuration Items: Control whether to check all CIs in the Affected CIs related list or only those on the change form.
Event Processing: Choose between running the refresh as a background event with notifications or in the current session without notifications.
Service Offerings and Business Applications Population: Automatically populate related lists from the Impacted Services/CIs related list based on configurations.

Key Outcomes

By configuring these properties, you can expect improved efficiency in managing impacted services during change requests. This allows for a more streamlined process in identifying relationships between CIs and enhances notification capabilities, ensuring all stakeholders are informed promptly of changes affecting services.

Understanding and utilizing these properties will help you optimize your ServiceNow instance, allowing for better service management and a clearer view of service dependencies during change operations.

Use the refresh impacted services properties to enable or disable the refresh impacted services capability, and to configure the criteria for additional refresh impacted services properties.

By configuring these properties, you can control the capabilities, such as:

Include the primary configuration item or all the items in the Affected CIs related list.
Processing of refreshing the impacted services as an event.
Populate Service Offerings and Business Applications from the Impacted Services related list.

The following properties can be found in sys_properties.list and on the Change properties page.

Table 1. Refresh impacted services properties
Property	Description
com.snc.change_request.refresh_impacted.include_affected_cis	When true, all the configuration items listed in the Affected CIs related list are checked. These configuration items are checked against the Application services mapping table (svc_ci_assoc) as this is a faster process, and also returns a more concise relationship picture. All the services from svc_ci_assoc table are retrieved. If the property is false, only the CI on the change form is used. This uses the method of traversing the cmdb tree structure to find the services. The services are retrieved from CIUtils script include. Note: If dynamic CI groups are used on the Change form, then this property must be set to true as the associations are located in the svc_ci_assoc table. When a business service is converted to an application service (as an example), all the levels included in the svc_ci_assoc table are considered at the time of conversion.
change.conflict.populateimpactedcis	If this property is set to true, then the ChangeCollisionHelper script include checks the configuration items that have been identified in the list of conflicts against the Application services mapping table (svc_ci_assoc) and also table (cmdb_ci_service) to check if there are any business services that are directly impacted.
com.snc.change_request.refresh_impacted.event	When true, the process of refreshing the impacted services is done through an event. This process is run in the background and you will be notified through a message in Notify that the process has been complete. When false, this is run in your session. As this is not run in background, there is no notification on completion.
com.snc.change_request.populate_service_offering	When true, the Service Offerings related list is populated from the Impacted Services/CIs related list. When false, the related list is not populated or amended in any way.
com.snc.change_request.populate_business_application	When true, the Business Applications related list is populated from the Impacted Services/CIs related list. When false, the related list is not populated or amended.
com.snc.change_request.refresh_impacted_services.message.show	When true, the `Refresh impacted services is initiated` message appears on the Change request form. When false, the `Refresh impacted services is initiated` message doesn't appear.
