    You can create multiple implementations for each extension point and provide an order number for each implementation. The implementation that has the lowest order number is the implementation that is executed.

    Table 1. Customer Service Management extension points
    Extension point Description
    sn_customerservice.CSMService Defines the default value logic for case objects.

    Available with the Customer Service (com.sn_customerservice) plugin.
    sn_customerservice.CSMCaseSync Use this extension point to customize the logic for parent-child case synchronization. This extension point can be used in one of two ways:
    • Define the conditions for parent case records that can be considered for synchronization to child cases. The default functionality is based on the sn_customerservice.parent_child_ case_sync system property. Customers can add additional conditions using this extension point.
    • Customize the logic for parent-child case synchronization based on the state of the child case. By default, if the child case is in the Resolved, Closed, or Cancelled state, there is no sync from the parent case.
    This extension point is used by the CSCaseSyncHelper script include and is available with the Customer Service (com.sn_customerservice) plugin.
    Note:
    In the base system, parent-child case synchronization is available only for the Case table (sn_customerservice_case). This feature must be configured for tables that extend the Case table.
