三总结

主要用到的知识点：
MODIF ID ：
以下是SAP官方给出的定义。
1.Effect
These additions can be used to declare the input field as a required field, hide the input field on the selection screen, and define the visible length of the field. The input field can be displayed as a checkbox, radio button, or dropdown list box. The MODIF ID addition assigns all the screen elements of the parameter to the modification group modid.
2.SCREEN-ACTIVE = ‘0’.
