Hi,
See this example of adding new field to sale order model.

In python side, inherit the model and add the field:
# -*- coding: utf-8 -*-

from odoo import api, fields, models

class SaleOrder(models.Model):
_inherit = "sale.order"

sale_description = fields.Char(string='Sale Description')
Then in the xml:  https://github.com/odoomates/odooapps/blob/14.0/om_hospital/views/sale.xml#:~:text=%3Crecord id%3D%22view_order_form_inherit,%3C/rec
