Why does CSV upload via "Map CSV to XDM schema" create new records instead of updating existing ones?

[dparraa]

Hi everyone,

When uploading a CSV file using the Map CSV to XDM schema option in Workflows, I included additional data of a empty columns to complement an existing record in the dataset. However, instead of updating the specified fields, a new record was created. Why does this happen, and is there a specific configuration I might be missing to ensure records are updated rather than duplicated?

Regards,

Diego P.

AEP is an additive platform, and whenever you ingest data, a new record is created. If you want to update existing records, you need to enable the dataset for profile updates, and use Upsert https://experienceleague.adobe.com/en/docs/platform-learn/tutorials/profiles/update-a-specific-attri...
