Thank you for your answare 

Hi,

For creating record in your "Pre-Packing" model when clicking button "Solicitar" from BOM table, you can just define a function like this which will trigger when clicking the button;

def solicitar_button_func()
    values = {
    'repair_order_id': self.repair_order_id.id,
    'user_id': self.user_id.id,
    'product_id': self.product_id.id
    }
    self.repair_order_related_field_in_BOM_table.write({
            'pre_packing_one2many_field': [(0,0, values)]
        })

Regards
