1、单条消息的输出

     普通消息输出方式每次只能输出最后一条消息，例如： message e001(vf).

2、多条消息的输出

需要用到函数组：MESSAGES_SHOW

TYPES:
  BEGIN OF ts_msg,
    msgty     TYPE msgty,
    msgid     TYPE msgid,
    msgno     TYPE syst_msgno,
    msgv1     TYPE msgv1,
    msgv2     TYPE msgv2,
    msgv3     TYPE msgv3,
    msgv4     TYPE msgv4,
    text      TYPE string,
    logsys    TYPE logsys,
    exception TYPE REF TO cx_root,
  END OF ts_msg,
  tt_msg TYPE STANDARD TABLE OF ts_msg WITH EMPTY KEY.
