problem in ps_order_detail when product in the order has a product_supplier_reference

[eleb]

Hello,

I would like to add  product_supplier_reference in the delivery slip PDF.  After some testing I found that in table ps_order_detail the field product_supplier_reference is empty even if the product has the supplier code (ps_product_supplier.product_supplier_reference).

I guessed that the field should be updated when the product is added to an order.
Am I wrong? Is this a bug?

Any suggestion?

thanks
