Can anyone say, how could we create dashboard for a view under My Dashboard menu? I need xml code of that. Can anyone help me out of this?

<?xml version="1.0"?>

<openerp>

<data>

       <record model="ir.ui.view" id="board_sales_purchases">

            <field name="name">Sales and Purchases</field>

            <field name="model">board.board</field>

            <field name="type">form</field>

            <field name="arch" type="xml">

            <form string="Sales and Purchase">

                <hpaned>

                    <child1>

                        <action string="Sales" name="%(action_invoice_tree2)d"

                            colspan="2" />   

                    </child1>

                </hpaned>

            </form>

        </field>

   </record>

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

        <field name="name">Sales and Purchases</field>

        <field name="res_model">board.board</field>

        <field name="view_type">form</field>

        <field name="view_mode">form</field>

        <field name="usage">menu</field>

        <field name="view_id" ref="board_sales_purchases" />

  </record>

  <menuitem id="menu_action_invoices_board" parent="board.menu_board_my_dash" action="action_invoices_board"/>

</data>

</openerp>

The above is the code, but it is not working. It is showing blank menu.
