## Summary of Refresh impacted services properties

The refresh impacted services properties in ServiceNow allow you to enable or disable the refresh impacted services capability and configure criteria that determine how impacted services are refreshed on change requests.
This functionality helps ensure accurate identification and updating of services affected by changes, improving change management visibility and impact analysis.

## Key Features

* **Include primary or all Affected CIs:** Decide whether to consider only the primary configuration item (CI) on a change or all CIs listed in the Affected CIs related list when refreshing impacted services.
* **Event-driven processing:** Optionally run the refresh process as a background event, allowing asynchronous processing with user notification on completion.
* **Populate related lists:** Automatically fill the Service Offerings and Business Applications related lists on the change request from impacted services based on CMDB relationships.
* **CMDB relationship reliance:** The properties depend on accurate CMDB relationships between impacted services, service offerings, business applications, and configuration items for proper roll-up and display.

## Configuration Properties and Their Practical Use

* **com.snc.changerequest.refreshimpacted.includeaffectedcis:** When true, all Affected CIs are checked against the Application services mapping table (svcciassoc) for efficient and concise service association retrieval. Set to true if using dynamic CI groups.
* **change.conflict.populateimpactedcis:** If true, the ChangeCollisionHelper checks conflicted CIs against service mappings to identify directly impacted business services.
* **com.snc.changerequest.refreshimpacted.event:** Enables running the refresh process as a background event with completion notification; false runs it synchronously without notification.
* **com.snc.changerequest.populateserviceoffering:** When enabled, populates Service Offerings related list from impacted services that have a "Depends on" or "Used by" relationship with impacted services.
* **com.snc.changerequest.populatebusinessapplication:** Populates the Business Applications related list from impacted services when set to true.
* **com.snc.changerequest.refreshimpactedservices.message.show:** Controls display of a notification message on the Change request form when the refresh process is initiated.

## Practical Impact for ServiceNow Customers

By configuring these properties, customers can optimize how impacted services are identified and displayed on change requests, ensuring accurate impact analysis and better communication of risks. Using event-driven refresh reduces user wait times, while automatic population of service offerings and business applications enhances visibility into service impact. Proper CMDB relationship maintenance is critical to leverage these features effectively.  
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.
{#refreshing-impacted-services-properties__ul_dxp_zzw_v4b}

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

The `com.snc.change_request.populate_service-offering` and `com.snc.change_request.populate_business_application` properties rely on CMDB relationships between the impacted service and its service
offerings or business applications. For an offering or application to be added it its related list, it must be associated with an impacted configuration item identified by the refresh process. For more information on how,
affected CIs roll up to impacted services, see [Associated CIs on a change request](https://www.servicenow.com/docs/cOw5ShTPsLii_G5xE_KYZg#c_AffectedCIsAndImpactedServices "You can associate additional CIs or services to change requests through related lists on the Change Request form. You can also associate CIs with a change request from the dependency views map.").

| 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. {#refreshing-impacted-services-properties__ul_uk2_l3x_v4b} 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. {#refreshing-impacted-services-properties__ul_kll_cgv_w4b} |
| `com.snc.change_request.populate_service_offering` | * When true, the Service Offerings related list is populated from the Impacted Services/CIs related list. A service offering is added only when it has a Depends on and Used by relationship with an impacted service in the CMDB. Offerings without this relationship to an impacted service are not added. * When false, the related list is not populated or amended in any way. {#refreshing-impacted-services-properties__ul_dlh_rgv_w4b} |
| `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. {#refreshing-impacted-services-properties__ul_fgl_cjv_w4b} |
| `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. {#refreshing-impacted-services-properties__ul_a2k_nvc_hsb} |
