        <record id="sale.action_orders" model="ir.actions.act_window">
            <field name="name">Sales Orders</field>
            <field name="type">ir.actions.act_window</field>
            <field name="res_model">sale.order</field>
            <field name="view_type">form</field>
            <field name="view_mode">tree,form,calendar,graph</field>
            <field name="search_view_id" ref="sale.view_sales_order_filter"/>
            <field name="context">{}
            </field>
            <field name="domain">[('state', 'not in', ('draft', 'sent', 'cancel'))]</field>
            <field name="help" type="html">
                <p class="oe_view_nocontent_create">
