You can enter the MPN, GTIN, etc. in the WooCommerce product data metabox when editing a product.

Hello JS Morisset thanks for your reply.
The issue is that when we go to product and inventory the GTIN number is missing but our supplier informs us that :
<< The information can be found in the metadata of the products, as we indicated. This means that third party software, such as Google Merchant, can read this data without you having to make any modifications or include the GTIN in your store’s back-office.
if you want to access this information manually, and you do not have programming skills, the easiest way would be to download a plugin that helps you to visualize the metadata of your store. There you will have to look for the products section, and you will be able to see the GTIN manually if you need to.>>

If you have the meta key name for that GTIN field, and you’re using the WPSSO Core Premium plugin, then you can enter the meta key name under the SSO > Advanced Settings > Attributes and Metadata > Custom Fields tab.
Alternatively, you can provider your supplier with the meta key name to use from those settings (for example, “_wpsso_product_gtin12” for a UPC, “_wpsso_product_gtin13” for an EAN, etc.).
