在项目中经常遇见需要查询生产订单在具体某个时间是什么状态，但是标准的function都是查询当前状态的，在此写下一个function查询具体某个时间点生产订单状态
先看结果，下图为测试结果，没有问题
源码如下

总结：IMPORT参数可输入单个生产订单及日期查询具体某个生产订单状态，也可在IT_AUFNR表输入许多生产订单及日期查询大量生产订单状态
function逻辑整体不复杂，已生产订单状态修改记录表JCDS为主体，简单的循环遍历状态，记录修改，最终取得生产订单状态。
程序中使用了查询内表获得输入生产订单中最大日期。
使用了活动内表记录生产订单所有的状态。
以上为查询特定时间下生产订单状态function，欢迎大家评论交流
