        <report auto="False"
                id="report12_sale_order"
                model="so.order"
                name="so.order"
                rml="sample/report_name/so_order.rml"
                string="vignesh"
                usage="default"/>

    </data>
</openerp>

the problem is when I click the print button, I am getting quotation/order and vignesh but I need to display only vignesh as pdf name

P.S I dont want to edit the name of the report in rml="sale/report/sale_order.rml" string="Quotation / Order" in base class.
