Update the date and operator according to the product unit not the order unit
Solution: If updating the order details, will update the order product as well. But If only updating the product order, will just update it. protected/actions/order/SaveByAjaxAction.php protected/actions/order/QueryForUseAction.php protected/services/OrderService.php
Display order products under the same order, even if we update the order products with different date times.
Solution: Change the sort order from op.update_time to o.update_time and display o.update_time at the same time. protected\actions\order\ExportExcelAction.php protected\actions\order\QueryForUseAction.php protected\services\OrderService.php ui\desktop\js\order.js
