获取sap登陆用户名的中文描述

一、业务场景：

当通过MKPF-USNAM查找ADRP-NAME_LAST时，中间缺少一个表，即USR21.否则，MKPF-USNAM不能和ADRP-PERSNUMBER直接对等。

二、解决方法：

 DATA:L_NAME_LAST LIKE ADRP-NAME_LAST,
      L_NAME_FIRST LIKE ADRP-NAME_FIRST.

 CLEAR:L_NAME_LAST,L_NAME_FIRST.

 SELECT
     adrp~persnumber
     date_from
     nation
     name_last
     name_first
     bname
 FROM adrp
 INNER JOIN usr21 ON adrp~persnumber = usr21~persnumber
 INTO TABLE it_adrp
 FOR ALL ENTRIES IN it_mkpf
 WHERE usr21~bname = it_mkpf-usnam.
