I'm using odoo 9 and I want to add two customized fields RC and Code_TVA in a report for the partner information . I have added Rc and Code_TVA in t-field-options but there is no difference. Any Help please ??

partner_view.xml

<?xml version="1.0" encoding="utf-8"?>
 <openerp>
 <data>
  <record id="res_partner_view_purchase_buttons_TVA_RC" model="ir.ui.view">
    <field name="name">num.TVA.RC.res.partner.view.purchase.</field>
    <field name="model">res.partner</field>
    <field name="inherit_id" ref="base.view_partner_form"/>
    <field name="arch" type="xml">
        <xpath expr="//field[@name='website']" position="after">
                    <field name="Code_TVA" select="1" placeholder="Code TVA"/>
                    <field name="RC" select="1" placeholder="Num RC"/>
        </xpath>
    </field>
  </record>
</data>
</openerp>

Partner.py

 class partner(models.Model):
 _inherit = 'res.partner'
 Code_TVA = fields.Char(string="Code de TVA")
 RC = fields.Char(string="Num Registre de Commerce")
