how can i add Internal Reference from image 1 (product) to image 2 (Order lines)

Answer 1

inherit sale.order.line and add a field

default_code = fields.Char(string='Internal Reference ', related="product_id.default_code")

add this default_code field in xml by inheriting the the order_lines view.
