1.以下是权限对象的定义

Authorization Objects
Authorization Object, as the name itself suggests, is a method of restricting users to access any particular application created in the system. It could simply be: denying user for viewing confidential data on-screen or denying access to certain Transactions.

权限对象
权限对象，在系统中是限制用户访问特别应用的一个方法。他可能简单的是:否定用户在屏幕上查看机密的数据，要么否决访问某一类代码.

2.权限对象的建立方法

1. 先输入事务代码(SU21)
2. 建了权限类后才能建权限对象，然后保存
   

3.新建权限对象

代码实现两个按钮

DATA exclusions TYPE STANDARD TABLE OF okcode.
AUTHORITY-CHECK for_button_1...
IF sy-subrc IS NOT INITIAL.
  INSERT c_okcode_for_button_1 INTO TABLE exclusions.
ENDIF
AUTHORITY-CHECK for_button_2...
IF sy-subrc IS NOT INITIAL.
  INSERT c_okcode_for_button_2 INTO TABLE exclusions.
ENDIF.
SET PF-STATUS 'MYSTATUS' EXCLUDING exclusions.
