If you turn on the Add Product Code (mpn) field. Then all the products without a GTIN and with the setting to FALSE (through custom fields) also get a MPN code. But google don't like this, see error below: When product identifiers are provided 'identifier_exists' should be set to true or not set at all. Setting identifier_exists to false when product identifiers actually exist might impact ranking of an item in the future. Would it be an idea for this situation to have a possibility to specify a separate product custom field for MPN and don't use the product code.

Kind regards, Lumiga ")* Hi, Yes, having the possibility to have a custom field for the MPN is something we want to add in the next version.
