In a duplicate pair of records,

Cloud MDM - Customer 360 for Salesforce

(

CC360

) considers the first record as the master record and the second record as the duplicate. The merge operation merges the duplicate with the master record and deletes the duplicate record. Ensure that the master record is the record that must survive. Use the

Toggle Master

button to specify the master record and the duplicate record.

The record you merge with the master record must not contain important information that is not present in the master record. To retain the data from some fields of the duplicate, specify whether the surviving data comes from the master record or from the duplicate record.
