Create wrapper to FM and handle the exceptions

Question

HI All
I need to create wrapper FM to fm BDC_RECORD_TRANSACTION like zBDC_RECORD_TRANSACTION.
the parameter should be the same and my question is how to handle the exceptions
do i need to keep the exception in the wrapper fm exactly the same i.e.
exactly the same signature for the exception and noting more or I need to add
additional coding to handle it .
CALL FUNCTION 'BDC_RECORD_TRANSACTION'
    EXPORTING
      tcode               = tcode
      authority_check     = 'X'
      OPTIONS             = ' '
      mode                = 'A'
      UPDATE              = 'A'
    TABLES
      dynprotab           = dynprotab
      messtab             = messtab
    EXCEPTIONS
      system_failure      = 1
      invalid_transaction = 2
      invalid_mode        = 3
      invalid_update      = 4
      OTHERS              = 5.
  IF sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
        WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.
Regards
Chris

HI
do you mean like this ?
CALL FUNCTION 'BDC_RECORD_TRANSACTION'
    EXPORTING
      tcode               = tcode
      authority_check     = 'X'
      OPTIONS             = ' '
      mode                = 'A'
      UPDATE              = 'A'
    TABLES
      dynprotab           = dynprotab
      messtab             = messtab
    EXCEPTIONS
      system_failure      = 1
      invalid_transaction = 2
      invalid_mode        = 3
      invalid_update      = 4
      OTHERS              = 5.
  IF sy-subrc <> 0.
    CASE sy-subrc.
      WHEN 1.
        RAISE system_failure.
      WHEN 2.
        RAISE invalid_transaction.
      WHEN 3.
        RAISE invalid_mode.
      WHEN 4.
        RAISE invalid_update.
      WHEN OTHERS.
    ENDCASE.
Thanks
Chris
