To enable advisors to capture Once-in-a-Lifetime events and prevent users from accidentally creating more than one event of such an event type,the consultant should configure Unique event types. Unique event types are event types that can only be created once for each contact or individual, such as birth, death, or marriage. By using Unique event types, the consultant can ensure that advisors cancapture important life events for their customers and avoid duplication or inconsistency.
