Checking Upsert on a Vlocity DataRaptor mapping can help prevent the creation of duplicate records.

• A. True
• B. False
• C. Sometimes
• D. Only for external IDs

Answer: (A)

Upsert works by using a key to locate an existing record before deciding whether to insert or update. In a Vlocity DataRaptor mapping, you configure an external ID (or a unique key) so the mapping can search Salesforce for a record with that key. If a match is found, the existing record is updated; if not, a new one is created. This behavior helps prevent duplicates because repeated data loads that share the same business key will update the existing record instead of creating a new one. For this to work reliably, you define a stable, unique key (commonly an external ID) on the target object. If that key isn’t unique or isn’t provided, duplicates can still slip in, but with proper external ID setup, checking Upsert in the mapping effectively reduces duplicate creation.
