1、SM02
创建消息，并设定有效期。当用户刷新窗口或打开窗口时会显示。
这个消息对client中的所有用户有效
2、So00中创建“到期邮件”
So00中创建一个普通邮件，在下面选择收件人，收件人后面有三个可选项，选中第一个(闪电标志)：到期邮件
邮件发出后，当用户刷新窗口或打开窗口时会显示。
3、用ABAP程序创建系统提示：这个提示的效果像是SAP系统出错时的提示，用户体验可能不够好，代码如下：
*&---------------------------------------------------------------------* *& Report YSENDMSG * *&---------------------------------------------------------------------* REPORT ysendmsg MESSAGE-ID zsd. DATA: list LIKE uinfo OCCURS 0 WITH HEADER LINE. DATA: mess LIKE sm04dic-popupmsg. PARAMETERS: p_mandt LIKE sy-mandt DEFAULT sy-mandt, p_user LIKE sy-uname, p_mess1(40), p_mess2(40), p_mess3(25), p_sender LIKE sy-uname DEFAULT sy-uname, p_time TYPE i DEFAULT '1'.
AT SELECTION-SCREEN. PERFORM check.
START-OF-SELECTION. CONCATENATE p_sender 'says:' p_mess1 p_mess2 p_mess3 INTO mess. CONDENSE mess. DO p_time TIMES. CALL FUNCTION 'TH_POPUP' EXPORTING client = p_mandt user = p_user MESSAGE = mess. ENDDO. *--------------------------------------------------------------------- * FORM check *--------------------------------------------------------------------- FORM check. CALL FUNCTION 'TH_USER_LIST' TABLES list = list. READ TABLE list WITH KEY bname = p_user mandt = p_mandt. IF sy-subrc <> 0. READ TABLE list WITH KEY bname = p_user. MESSAGE e001 WITH 'the user not on this client, but in' list-mandt. ENDIF. ENDFORM. " check
