Survivorship configurations contain rules, source system ranks, block survivorship and deduplication criteria. You must configure survivorship for business entities before users create records.
The survivorship configuration of a field determines the trust score, which indicates the confidence level in the field values. A higher trust score indicates greater confidence in the field value. Before you configure survivorship, understand key concepts, such as source ranking, rules, the source last updated date, block survivorship, and deduplication criteria.
