ABAP权限检查，TCode与权限对象进行关联

一、确认权限对象，和关联字段：

Tcode：SU21 维护权限对象
例如"M_MSEG_WMB",它关联字段为'WERKS'
M_MSEG_WMB 物料凭证：工厂

 

二、在ABAP代码中添加权限检查代码：
 

PROGRAM YTEST_13_001.

Tcode：SE38

TYPES: BEGIN OF ty_check_au,
werks TYPE mseg-werks,
END OF ty_check_au.
DATA: wa_check_au TYPE ty_check_au,
it_check_au TYPE TABLE OF ty_check_au.

AT SELECTION-SCREEN.
* 在此进行权限对象的检查
SELECT
werks
FROM mseg
INTO TABLE it_check_au
WHERE mblnr IN s_mblnr AND
werks = p_werks
AND mseg~bwart IN ('101','102','105','106').

LOOP AT it_check_au INTO wa_check_au.

AUTHORITY-CHECK OBJECT 'M_MSEG_WMB'
         ID 'ACTVT' FIELD '01'
         ID 'WERKS' FIELD wa_check_au-WERKS.
IF SY-SUBRC <> 0.
* Implement a suitable exception handling here
  MESSAGE E000 WITH '您没有工厂' LW_MARC-WERKS '的权限'.
ENDIF.

CLEAR wa_check_au.
ENDLOOP.

 

AUTHORITY-CHECK OBJECT 'M_MSEG_WMB'
         ID 'ACTVT' FIELD '01'
         ID 'WERKS' FIELD wa_check_au-W
