Duplicate Rules #inSalesforce

This defines what happens when a user views a record with duplicates or starts creating a duplicate record. You can create one.

Salesforce provides standard duplicate rules for business and person accounts, contacts, and leads.

Each standard duplicate rule includes a corresponding standard matching rule that determines how records are identified as duplicates.
