Hi all, I have been trying to override the left menu item "Quotations" in the Purchases Module (making domain changes) and am having touble. I copied the code and inherited, but instead of overriding the menu item it creates a new menu item. Is there a way to just override it instead? This is what my code looks like currently:

        <record id="purchase_rfq" model="ir.actions.act_window">

            <field name="name">Quotations</field>

            <field name="type">ir.actions.act_window</field>

            <field name="inherit_id" ref="purchase.purchase_order_tree"/>

            <field name="res_model">purchase.order</field>

            <field name="context">{}</field>

            <field name="domain">[('state','in',('draft','sent','confirmed')),('origin','=','')]</field>

            <field name="view_mode">tree,form,graph,calendar</field>

            <field name="search_view_id" ref="purchase.view_purchase_order_filter"/>

            <field name="help" type="html">

              <p class="oe_view_nocontent_create">

                Click to create a request for quotation.

              </p><p>

                The quotation contains the history of the discussion/negociation

                you had with your supplier. Once confirmed, a request for

                quotation is converted into a purchase order.

              </p><p>

                Most propositions of purchase orders are created automatically

                by OpenERP based on inventory needs.

              </p>

            </field>

        </record>

        <menuitem action="purchase_rfq" id="menu_purchase_rfq"

            parent="purchase.menu_procurement_management"

            sequence="1"/>
