CIS-CSM: Certified Implementation Specialist - Customer Service Management

Major Issue Management supports a major (parent) case with associated child cases, and administrators can configure the list of fields synchronized from the parent case to its child cases. Synchronization is not performed when a child case is Resolved, Closed, or Canceled. The synchronization setting is a configurable system property rather than an automatically enabled capability.
