# Auto Mapping

Auto mapping links source fields to catalog fields in the following scenarios:

* **Exact Match with an Existing Catalog Field**
* **Mapping Based on Previous Associations**

### Scenario 1: Exact Match with an Existing Catalogue Field

When you create a Catalogue field in Zeotap CDP, the field name becomes an auto-mapping parameter. If an incoming source field matches the Catalogue name, then enabling auto mapping links them them automatically.

**Example**

* You create a Catalogue named **artist\_name**.
* A new source file also contains a field named **artist\_name**.
* In this case, enabling Auto mapping links the source field **artist\_name** to the Catalogue field **artist\_name** without manual intervention.

### Scenario 2: Mapping Based on Previous Associations

If a source field was previously mapped to a Catalogue field, auto-mapping applies the same mapping when the field appears in a new source.

**Example**

* You previously mapped the source field **product\_type** to the Catalogue field **category**.
* If a new source file contains the field **product\_type**, \*\*\*\* then \*\*\*\* auto mapping suggests linking **product\_type** to **category**, following the previous mapping.
