安装后默认按时间降序排列：销售订单、采购订单、发货单、入库单、形式发票。

贴一下主要代码：
ordered.py

from osv import fields, osv

class purchase_order(osv.osv):
    _inherit = "purchase.order"
    _order = 'date_order desc, id desc'

purchase_order()

class sale_order(osv.osv):
    _inherit = "sale.order"
    _order = 'date_order desc, id desc'

sale_order()

class stock_picking(osv.osv):
    _inherit = "stock.picking"
    _order = 'date desc, id desc'

stock_picking()

class stock_move(osv.osv):
    _inherit = "stock.move"
    _order = 'date desc, id desc'

stock_move()


class account_invoice(osv.osv):
    _inherit = "account.invoice"
    _order = 'date_invoice desc, id desc'

account_invoice()
