Hi Mauro,

It will be better to go ahead with description, make the description field as the combination of the three, in the onchange of the products you can write the values to description.

If you use this method you don't want to add further changes in the report, as already the description is there in the report.

If you are adding the two new fields separately, then you have to write the values into these fields while changing the product , also you have to customize the report to add this fields in it.

So it will be better to go ahead with the first solution.

class PurchaseOrderExtend(models.Model):
    _inherit = 'purchase.order.line'

    @api.onchange('product_id')
    def SetDescriptions(self):
        if self.product_id:
            self.name = self.product_id.display_name + self.product_id.new_field_1 + \
                        self.product_id.new_field_2
            self.price_unit = self.product_id.lst_price

Thanks

thanks,

i agree, now i just need to understand how to modify the code exactly
