What is the primary function of Salesforce duplicate rule functionality?

The primary function of Salesforce duplicate rule functionality is to identify and manage duplicate records. This functionality is crucial for maintaining data quality within Salesforce, as duplicates can lead to confusion, inefficiencies, and inaccurate reporting. By setting up duplicate rules, organizations can specify criteria for what constitutes a duplicate and take desired actions when duplicates are detected, such as blocking the creation of a duplicate record or alerting users about the duplication.

This proactive approach to data management helps ensure that every record is unique and accurate, ultimately contributing to better decision-making and improved customer relationship management. The other options focus on unrelated functions; they do not pertain to the core purpose of preventing or managing duplicate records within the system.
