The module adds an MPN column in the invoice to the OpenCart order. For each product item in the invoice, the value from the MPN field will be displayed. If necessary - you can rename the column header in the modification.
The extension works when viewing accounts in the admin in the Orders section. The MPN in the invoice will be displayed as plain text in a separate column of the products table.
If you are printing invoices and need to add values from the MPN field, use this extension.

Upload the module in the admin panel in the "Extensions" : "Install".
