description: How Shopware 6 system product properties work and why exact internal field names are required during import.
---

Each Shopware 6 product is defined by multiple fields, such as "Name", "Product Number", and "Manufacturer." These fields, also known as product properties or attributes, are stored in the database with specific internal names that do not allow spaces.

When importing products, you are directly interacting with the database, so it's crucial to use the exact names of these properties as they appear in the database. For example, "Manufacturer" is stored as `manufacturer_id`, and Product Number is `product_number`. You can refer to an exported file to see how different properties are named.

This is essential because when importing, the column headers in your file must match the internal names of product properties in Shopware to ensure that the data is correctly mapped to the corresponding fields.
