Hi Meili Noni,

If you want to show detail Phone/Mobile number of partner in sale order then you need to add new field which is related to partner's Phone/Mobile number and using xpath you can put it in existing sale order form view.

Thanks & Regards,

Hi,
You can add the field phone number to the sales order by following the code given below.

Python:

class SaleOrder(models.Model):
        _inherit = "sale.order"
 
       phone = fields.Char(related='partner_id.phone', string='Phone')

XML:

<record id="sale_order_form_inherits" model="ir.ui.view">

            <field name="name">sale.order.form.inherit</field>

            <field name="model">sale.order</field>

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

            <field name="arch" type="xml">

                <xpath id="">

                    <xpath expr="//field[@name='partner_id']" position="after">

                        <field name="phone" widget="phone"/>

                    </xpath>

                </xpath>

            </field>

        </record>
