class SaleOrder(models.Model):
_name='sale.order'
_inherit = 'sale.order'
warehouse_id=fields.Many2one("stock.warehouse")

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <data>
        <record id="view_sale_form_inherit" model="ir\.ui\.view\"\>
\ \ \ \ \ \ \ \ \ \ \ \ \<field\ name=\"name\"\>sale.order.inherit</field>

            <field name="inherit_id" ref="sale.view_order_form"/>
            <field name="arch" type="xml">
