odoo - 'Field origin does not exist'

This is my code:

   <record id="view_order_form_inline" model="ir.ui.view">
            <field name="model">sale.order.line</field>
            <field name="inherit_id" ref="sale.view_order_form"/>
            <field name="arch" type="xml">
                <xpath expr="//field[@name='order_line']/tree/field[11]" position="after">
                    <field name="xx_insurance_inline"/>
                </xpath>
            </field>
        </record>

This is to add a new column inside the sales order lines. When updating my module i get the following error:

ParseError: "ValidateError
Field(s) `arch` failed against a constraint: Invalid view definition

Error details:
Field `origin` does not exist

Error context:

<record id="view_order_form_inline" model="ir.ui.view">
            <field name="model">sale.order.line</field>
            <field name="inherit_id" ref="sale.view_order_form"/>
            <field name="arch" type="xml">
                <xpath expr="//field[@name='order_line']/tree/field[11]" position="after">
                    <field name="xx_insurance_inline"/>
                </xpath>
            </field>
        </record>

Since there is nowhere in my code a reference to a field called origin I have no idea what the exact problem is. Should adding the column be done in a different way or am i overlooking something obvious?
