Hi,

I want to display the BOMs related to a product in the sale order line like so :

I've tried this :

bom_id = fields.Many2one("mrp.bom",string="Bill Of Material")

OR

bom_id = fields.Many2one("mrp.bom", related"product_id.bom_id.product_tmpl_id", string="Bill Of Material")

OR

bom_id = fields.One2Many("mrp.bom", "product_id", string="Bill Of Material")

Any idea ? Thanks in advance
