Product Category mapping allows to add Categories to existing Products.
You must create Products and Categories before you can assign products to these categories. This template will not create Products, if such don't exist.
Possible Entity Keys
Product Category mapping supprots ID, SKU, GTIN, Manufacturer part number or Name of Product as entity key.
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.
