# Create a Catalog Field Mapping

To ensure that catalog heading names are mapped to the required application field names, create a catalog field mapping in Einstein Recommendations.

1. Click **Field Mapping**.
2. Review the fields for mapping accuracy.
3. To change, expand the selection box under Your Headings and change the selections listed in the catalog heading names.
    
    Unique catalog headings are required for each field. Duplication of a heading automatically deletes the heading from the previously mapped field.
4. For **Additional Fields**, indicate whether the mapping accepts multiple values.
5. Select the tagged fields.
6. Select fields to use for personalization.
7. Select a data format that matches the date field in your catalog.
8. Save your changes.
