小弟用PB做了个订单上传的软件，用于公司的各销售人员向服务器上传自己的订单，用的是数据管道。
现在主管要求添加如下功能：
每个订单都有个Complete字段（Y/N）来标识订单填写是否正确。当订单上传时，Complete默认是Y，服务器端会有专门人员来审核订单，如发现订单有错，则将该字段改为N。
销售人员需要从服务器中搜索自己上传的那些审核未通过（即Complete为N）的订单，并下载到本机上覆盖原订单，修改后重新上传。
订单中有专门一列add_emp来标识不同的销售人员，即销售人员自己的编号。
小弟接触PB时间不久，不知红字部分功能如何实现，望指教～
------解决方案--------------------
在你软件上 写个TIMER事件：用游标，做下面检索
SELECT ooxx into :ls_OOXX FROM 订单表 where add_emp = 当前销售 and Complete =N
检索结果放到一个数据窗口里，这样那边有审核没通过的当场就可以弹出列表了。
审核没通过，订单信息没变，不涉及到覆盖啊，根据列表改下本地订单表状态就好了，默认是Y 改成N
是这个意思不？

管道可以写where条件，而且pb里有pipeline对象，可启动管道，并带参数
