Hello I need change the orientation of the report on qweb-pdf. I am following the documentation making a record, but I don't understand why is this ignored. Here is the XML

     <report
        id="report_asiento_contable"
        model="account.move"
        string="Asiento contable"
        name="velfasa.report_asiento_contable_view"
        file="velfasa.report_asiento_contable"
        report_type="qweb-pdf" />
    <template id="report_asiento_contable_view">
        <xpath expr="//style" position="after">
            <style type="text/css" >
                .tabla {
                    cellpadding: 10;
                    border: 1px solid black;
                }
            </style>
        </xpath>
        <t t-call="report.html_container">
            <record id="paperformat_asiento_contable" model="report_asiento_contable.paperformat">
                    <field name="name" >Asiento contable</field>
                   <field name="orientation" >Landscape</field>
            </record>

       </t>

  </template
