After you process the initial data in Customer 360, create an egress job to export all the master records from Customer 360 to Salesforce. By default, you can export the records that have been created, updated, and merged in Customer 360 to Salesforce.
When you export the master records to Salesforce, the values of each duplicate record in Salesforce are updated with the master record value. Each master record in Salesforce gets a Customer360 Id that maps to the business ID of the master record.
The Customer360 Sync Date fields for the master records, which display the export dates, are updated accordingly in Salesforce.
