# Product Manufacturer mapping

{% hint style="danger" %}
You must create [Products ](https://importmanager.docs.foxnetsoft.com/column-mappings/product)and [Manufacturers](https://importmanager.docs.foxnetsoft.com/column-mappings/manufacturer) before you can assign products to these categories. This template **will not** create Products, if such don't exist.
{% endhint %}

## Possible Entity Keys

Product Category mapping supprots ID, SKU, GTIN, Manufacturer part number or Name of Product as entity key.

{% hint style="warning" %}
Your entity key must be unique. If you have two products with same Name fields, you will not be able to use Name as entity key.
