abap TRY catch 抓不到消息

问题:今天写了个F.80的需求, 参考标准代码加了校验,发现了一个很奇怪的问题,那就是如果函数抛出的异常抓不到怎么办!(有关异常的相关知识可以参考异常处理),参考以下代码,会发现即使使用cx_root也抓不到message.(是带参数的message,不是直接raise exceptions,看下图)

  DATA:X_DIALOG TYPE C." VALUE 'X'.
  TRY .

    CALL FUNCTION 'FI_ACCOUNT_CHECK'
      EXPORTING
        I_BUKRS                = P_GS_OUTPUT-RBUKRS
        I_KOART                = P_GS_OUTPUT-KOART
        I_ACCOUNT              = P_GS_OUTPUT-RACCT
        I_RECACCOUNT           = P_GS_OUTPUT-RACCT                   "NOTE 323557
        I_WAERS                = P_GS_OUTPUT-RHCUR
        I_TCODE                = 'FB08'
        X_DIALOG               = X_DIALOG   "WARNUNGEN IM DIALOG
      EXCEPTIONS
        ACCOUNT_LOCKED                      = 1
        CURRENCY                            = 2
        NO_RECONCILIATION_ACCOUNT           = 3
        RECONCILIATION_ACCOUNT              = 4
        RECONCILIATION_ACCOUNT_LOCKED       = 5
        .
  CATCH CX_SY_DYN_CALL_ILLEGAL_FUNC INTO DATA(LT_CX_FOEV_ERROR_IN_FUNCTION).
*      EXPORT
*          EBUF0002 BUFFER_ID_DATE BUFFER_ID_TIME
*             TO SHARED BUFFER CONTEXTB(EB) ID BUFFER_ID.
  ENDTRY.

  IF SY-SUBRC NE 0.
    P_LV_ERROR = 'X'.
  ENDIF.

解决:那么有没有什么好办法能抓到message呢?既然文章发出来,那当然是有了。其实很简单,再endtry后面加个判断就好了

  IF sy-subrc <> 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
            WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ENDIF.
