ABAP历险记

1.本文操作有很大风险，请把文章看完整再进行测试操作

2.背景

这几天在研究FIORI的登陆问题，想从微信公从号打开FIORI APP，然后用公众号的安全验证来验证SAP用户的有效性，比如 SICF设置FIORI APP默认用A账号（低权限，读取数据都不行），从公众号中打开此APP地址，在ABAP中通过公从号传来的验证code连接公众号验证有效，并得到用户微信信息（微信号，手机号等），此时可通过这些信息来做处理，比如登陆紧急用户访问（/GRCPI/GRIA_EAM）来切换更大权限的不同的账号来实际操作，

总体来说就是研究SAP的登陆逻辑，结果在网络上找到一文章说，登陆逻辑在程序SAPMSYST中，而我用SE38打开此程序查看时，报“受保护”，不能打开，而我也没细看文章的后文，刚好我自己有一个可以随意查看程序的程序（Z_EDIT代码后附），结果悲剧了，Z_EDIT打开SAPMSYST，原来想着只要不保存，也不会有问题，但Z_EDIT没有考虑到受保护的情况，SAPMSYST被清空了，SAP GUI无法登录，ST22产生大量DUMP，情况紧急。

3.修改程序的程序Z_EDIT

REPORT Z_EDIT.
data: begin of itab occurs 0,
        line(200).
data: end of itab.

parameters: progrmm(50).
*delete report progrmm.
*PERFORM RECORD_USAGE IN PROGRAM ZZ001
*                                    USING SY-CPROG.

  read report progrmm into itab.
  editor-call for itab.
  insert report progrmm from itab.

REPORT Z_EDIT.

data: begin of itab occurs 0,

line(200).

data: end of itab.

parameters: progrmm(50).

*delete report progrmm.

*PERFORM RECORD_USAGE IN PROGRAM ZZ001

* USING SY-CPROG.

read report progrmm into itab.

editor-call for itab.

insert report progrmm from itab.

我只用此程序查看了一下SAPMSYST，没有保存，但系统就登陆不上了。吓得我心跳100下，在网上各种找资料，才找到的解决办法，

4.解决办法

我出问题的系统是DEV，所以前三步是在QAS上执行，最后一步是在DEV上执行

1.创建一个空程序 ZSAPMSYST
2.通过DB02 的SQL语句把SAPMSYST的代码写入到 ZSAPMSYST .
UPDATE REPOSRC SET DATA = ( SELECT DATA FROM REPOSRC WHERE PROGNAME = ‘SAPMSYST’ ) WHERE PROGNAME = ‘ZSAPMSYST’
3.用SE38 查看ZSAPMSYST 代码就可以看到标准程序SAPMSYST的代码了.
4.把ZSAPMSYST的代码复制到Z_EDIT中，覆盖回去。

不幸中的万幸是，我出问题后没有退出DEV，第四步，我还能在DEV中执行，如果我退出了DEV，那第四步，我要如何在DEV中执行呢？

5.SAPMSYST程序的代码

顺便也把我从QAS上获取的SAPMSYST程序的代码放一下，我的SAP版本是SAP S/4HANA 2020（SAPK-75502INSAPBASIS），

6.关于FIORI登陆的思考

FIORI登陆可以在SICF中配置自定登陆的一些信息，并配置使用自定类登陆，类：/UI2/CL_FIORI3_LOGIN，可以网上找到相关的信息
当FIORI登陆后，刷新数据时，第一步调用类/IWFND/CL_SODATA_HTTP_HANDLER，方法：IF_HTTP_EXTENSION~HANDLE_REQUEST，当执行263行mo_rest_handler->if_http_extension~handle_request( server ).后变量lo_transaction_handler，的-MT_ALL_REQUEST_PARAMS[7]-NAME = referer时，值会是完整的URL，其中可能包含传的参数（如：https://*****:1443/sap/bc/ui5_ui5/sap/zconsign_sale/index.html?sap-client=130&sap-language=ZH&code=AAAAAAAAAAAAAAAAA）
考虑前一步方法结束时，判断referer的值如参数中包含code参数，则连接微信公从号判断此code,是否有效，有效时并使用 GRC EAM应急账号登陆（事务码：/N/GRCPI/GRIA_EAM）
登陆参数/grcpi/gria_cl_remote_login=>remote_login，里面有创建SM59连接，修改，删除连接功能，还有打开连接的功能。但这个感觉是在GUI中新开一个窗口用新账号登陆，不知这能不能在当前窗口把登陆账号换成新账号登陆，有待验证
或者是在这里验证CODE，并记录微信相关系统到自定义，并在后面的取数，或者更新数据时使用远程RFC（先判断是微信URL并有效）的方式操作数据，

  CALL FUNCTION 'SYSTEM_REMOTE_LOGIN'                "#EC CI_USE_WANTED
    EXPORTING
      destination   = lv_logical_dest
    IMPORTING
      error_message = lv_emsg
    EXCEPTIONS
      cannot_start  = 1
      OTHERS        = 2.

CALL FUNCTION 'SYSTEM_REMOTE_LOGIN' "#EC CI_USE_WANTED

EXPORTING

destination = lv_logical_dest

IMPORTING

error_message = lv_emsg

EXCEPTIONS

cannot_start = 1

OTHERS = 2.
