在sap扩展中用户往往都需要使用自己的权限对象，为了达到次目的，请按下列步骤建立和维护权限对象
1、Create an Anthorization Field（SU20）创建权限对象字段（存储在AUTHX表中）
2、Create an Authorization Object（SU21)创建权限对象
创建权限对象类别（存储在TOBCT表中）
点击对象类别创建权限对象（存储在TOBJ表中），生成SAP_ALL
3、Assign an Authorization Object to an Object Class(SU02或PFCG)
4、权限赋值关系图
user master record
/ ..............................\
auth. profileComposite auth. profile
/.................\ / \
/ \ / \
Authorization Auth. Profile
/ /.................\
5、Call "Authorith-Check" in Program to Check Authorization.
这是我编写针对具体权限对象替代Authorith-Check的函数

z_return = 4.
select ust04~profile usr10~typ
