Hi

I've created and displayed a simple module that creates a selection drop down menu in sales.order .... Big smiley face :)

However ...  :(

Question 1 How do I display this value in stock.picking - None editable?

Question 2 How do  I display this value in account.invoice - and editable?

from odoo import fields, models

class SaleHoldNoteModel(models.Model):
    _inherit = 'sale.order'

    #Create new field containg note for shipping
    shipping_note = fields.Selection([
        ('oktoship', 'Ship'),
        ('awaitingpayment', 'Hold')], default='oktoship')

<?xml version="1.0" encoding="utf-8" ?>

<odoo>
  <record id="add_field_shipping_sales" model="ir.ui.view">
    <field name="name">shipping_hold</field>
    <field name="model">sale.order</field>
    <field name="inherit_id" ref="sale.view_order_form"/>
    <field name="arch" type="xml">
      <xpath expr="//field[@name='payment_term_id']" position="after">
        <field name="shipping_note"/>
      </xpath>
    </field>
  </record>
</odoo>

I tried creating a copy of the above but keep getting field not known 

Do I have to transfer the field and value between models?
