本文介绍如何在SAP系统中记录用户登录时的IP地址，并实现IP地址与R/3用户名的绑定。首先，通过增强代码记录登录信息至自定义表ZLOGONINFO；其次，创建用户与IP地址的对应表USERLOGON并验证登录时的用户名及IP地址是否匹配。

作用：

一.登陆时候记录用户的IP地址等信息

二.登陆时候与用户IP地址绑定登陆

登陆SAP实现IP地址记录和绑定

一.登陆时候记录用户的IP地址等信息首先在系统建立数据库表ZLOGONINFO记录用户登陆信息,包括信息(R/3用户名/终端名/IP地址/登陆日期/登陆时间). 其次在R/3用户登陆增强(SUSR0001)写代码记录用户相关的信息到数据库表ZLOGONINFO,完成用户登陆信息的记录增强代码如下:

INSERT INTO ZLOGONINFO CLIENT SPECIFIED VALUES ZLOGONINFO.
二.登陆时候与用户IP地址绑定登陆首先在系统里建立R/3用户和IP地址的对应的关系表USERLOGON,包括信息(R/3用户名/IP地址),然后通过批导入的方式将对应关系数据导入系统表里. 其次在R/3用户登陆增强(SUSR0001)写代码验证用户登陆时候的R/3用户名和IP地址在系统对应关系表里是否有,通过则允许登陆,未通过则不允许登陆. 增强代码如下:
CALL FUNCTION 'TH_USER_INFO'
IMPORTING HOSTADDR = HOSTADR "like UINFO-HOSTADR (hex)
HOSTADDR = HOSTADR.
DO 4 TIMES.
HX = HOSTADDR+ITIMES1(2).
ITIMES = 0.
RESULT = 0.
DO 2 TIMES.
CASE HX+ITIMES(1).
WHEN 'A'.
IF ITIMES = 0.
RESULT = RESULT + 10 * 16.
ELSE.
RESULT = RESULT + 10.
ENDIF.
WHEN 'B'.
IF ITIMES = 0.
RESULT = RESULT + 11 * 16.
ELSE.
RESULT = RESULT + 11.
ENDIF.
WHEN 'C'.
IF ITIMES = 0.
RESULT = RESULT + 12 * 16.
ELSE.
RESULT = RESULT + 12.
ENDIF.
WHEN 'D'.
IF ITIMES = 0.
RESULT = RESULT + 13 * 16.
ELSE.
RESULT = RESULT + 13.
ENDIF.
WHEN 'E'.
IF ITIMES = 0.
RESULT = RESULT + 14 * 16.
ELSE.
RESULT = RESULT + 14.
ENDIF.
WHEN 'F'.
IF ITIMES = 0.
RESULT = RESULT + 15 * 16.
ELSE.
RESULT = RESULT + 15.
ENDIF.
WHEN OTHERS.
IF ITIMES = 0.
RESULT = RESULT + HX+ITIMES(1) * 16.
ELSE.
RESULT = RESULT + HX+ITIMES(1).
ENDIF.
ENDCASE.
ITIMES = ITIMES + 1.
ENDDO.
RESULTTXT = RESULT.
IF IPTXT <> ''.
CONCATENATE IPTXT '.' RESULTTXT INTO IPTXT.
ELSE.
IPTXT = RESULTTXT.
ENDIF.
ITIMES1 = ITIMES1 + 2.
ENDDO.
SELECT COUNT(*) INTO XHCOUNT FROM USERLOGON WHERE BNAME = SY-UNAME
AND IP = IPTXT.
IF XHCOUNT < 0.
MESSAGE I003(ZTXBHB).
CALL 'SYST_LOGOFF'."退出SAP系统
ELSE.
MESSAGE I002(ZTXBHB).”登陆
ENDIF.
