需求

如图,当我点击责任工序的搜说帮助时,
同时会把责任人员的描述带出来.

解析

1-DYNP_GET_STEPL

这个方法就是获取当前的循环步骤

2-F4IF_INT_TABLE_VALUE_REQUEST

这个函数就是搜索帮助功能的函数,这里主要说一下这个参数RETURN_TAB返回值,
他会返回你所想要的字段值.

3-获取返回值

这个红框中就是我想要这个字段的具体内容,然后通过这个字段值我来获取责任人员的数据.

4-把相应字段更新到内表

这个就是你要把那些值带到屏幕上去,可以带出多个字段,一直加就行了.

5-DYNP_VALUES_UPDATE

这个函数的作用就是更新字段的, 把刚才你添加的那两个字段更新到屏幕上去.

欢迎大佬前来补充
