In sales during customer creation,

In model res.partner I have included a field Is a agent.If the customer is a agent then commission amount will be asked.Otherwise,invisible

In Sale Orders,

In model sale.order I have to get the commision amount if the customer entered is a agent..

How to get that...

My model res.partners inherited is-

from odoo import models, fields, api


#Model of Agent-Commision
class agent_comission(models.Model):
    _inherit = 'res.partner'
     
    agent = fields.Boolean(string='Is a Agent',default=False)
    commission_amount = fields.Integer(string='Commission Amount',store=True)

agent_name = fields.Many2one(
      comodel_name="res.partner", required=True,
      domain="[('agent', '=', True)]")

My View is of res.partner inherited:-

<?xml version="1.0" encoding="UTF-8"?>
<odoo>
    <data>
<record model="ir.ui.view" id="view_agent_form">
    <field name="name">res.partner.form.inherit</field>
    <field name="model">res.partner</field>
    <field name="inherit_id" ref="base.view_partner_form"/>
    <field name="arch" type="xml">
        <field name="website" position="before">
            <field name="agent"/>
            <field name="commission_amount" attrs="{'invisible': [('agent', '=',False)]}"/></field>
    </field>
</record>

How to implement it..
