When you create a data product, Tamr Cloud automatically maps the predefined output fields to the mastered entity field names that display in Studio, Curator, and published datasets.

Important: Do not edit or remove the field for entity_ID.

In the Deliver to Studio mastering step, you can customize fields for display in Studio, Curator, and published datasets as follows:

• Rename the entity fields.
• Add new entity fields for any new output fields you added, and map output fields to these entity fields. New fields must be added one at a time.
• Add, edit, and reorder field groups. Fields in the primary group are included in the entity table in Studio and Curator. View fields in all other groups by selecting a mastered entity from the Studio entity table. You can also view the complete field list in the Fields page in Studio.

Important: The field names you specify in the Deliver to Studio step are included in the published datasets. Ensure that the field names conform to any requirements from downstream systems.
