一般的Dynpro程序，Enter Key （回车） 不改变sy-ucomm! 这是标准Dynpro的要求。也是为什么在很多情况下按回车没有反应。要知道sy-ucomm的值，你必须读源程序，在screen PAI event module 中找OK_CODE 或sy-ucomm （常见的是 OK_CODE = sy-ucomm)，放个break point, debug一下。
点击屏幕上的按钮时，SY-UCOMM这个系统字段会记录当前点击按钮的功能代码，BU一般作为系统的保存按钮的功能代码，SY-UCOMM='BU'就表示用户点击保存
subrc是系统标准表SYST的一个字段，记录上一条语句的执行的状态，sy-subrc=0表示上一条语句执行正确，sy-subrc为其他值表示上一条语句执行出错。callfunction'''引号里跟函数名，表示调用函数，可以是自定义的，也可以是系统的~~
