Add field to inherited tab view

Question

i try to add a field in the tab view accounting. But if i access the view it throws following exception:

Fehler bei der Validierung der Ansicht nahe:

                </div>
                <div class="alert alert-warning oe_edit_only" role="alert" name="warning_company" invisible="not same_company_registry_partner_id">
                  A partner with the same <span><span class="o_vat_label">Company Registry</span></span> already exists (<field name="same_company_registry_partner_id" context="{'show_address': False, 'show_vat': False}"/>), are you sure to create a new one?
                </div>
                    <div groups="account.group_account_invoice,account.group_account_readonly" class="alert alert-warning" role="alert" invisible="duplicated_bank_account_partners_count == 0">

    action_view_partner_with_same_bank ist keine gültige Aktion für res.partner

But i don´t wanna add anything! This view already exists and is a view from odoo self. My view to add a field likes following:

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <record id="heinzmann_res_partner_view_form" model="ir.ui.view">
        <field name="name">res.partner.view_form</field>
        <field name="model">res.partner</field>
        <field name="type">form</field>
        <field name="inherit_id" ref="account.view_partner_property_form"/>
        <field name="arch" type="xml">
            <xpath expr="//page[@name='accounting']" position="inside">
                Automatische Rechnung am Ende des Monats:<field name="x_auto_invoice_at_end_of_month"/>
            </xpath>
        </field>
    </record>
</odoo>

What i have to do to add a simple field?

Here the full error message:

The above server error caused the following client error:

If i add the same field to the base.view_partner_form it works fine.
