hi,

i run FM 'CONVERT_DATE_TO_EXTERNAL' to test the exceptions but no matter what i pass in, even an invalid date i still not able to go in exceptions.

i actually would like to see what is these 1 and 2. thx

1) what is 1 and 2? are they sy-subrc? what if sy-subrc is 4?

2) what is this 'OTHERS' under the exceptions in the call function below?

3) why i simply enter an invalid date like '10022031' in yyyymmdd format, sy-subrc still 0?

in abap :

CALL FUNCTION 'CONVERT_DATE_TO_EXTERNAL'

EXPORTING

date_internal = p_date

IMPORTING

date_external = p_outdate

EXCEPTIONS

date_internal_is_invalid = 1

OTHERS = 2.

in FM :

CASE SY-SUBRC.

WHEN 0.

DATE_EXTERNAL = H_DATE_EXTERNAL.

WHEN OTHERS.

MESSAGE E650 RAISING DATE_INTERNAL_IS_INVALID.

Bitte gültiges internes Datum angeben (JJJJMMTT)

ENDCASE.

whenever you use the FM, the exception numbers are actuallty the sy-subrc value.

You require to check the sy-subrc and display message accordingly.

Others is the default exception attach with all FM.

Since there are some uncounted errors may occur like OS failure to name.

Soeverytime u use a FM handle these sy-subrc or exceptions accordingly.

If sy-subrc is 0 means success.

Regards,

Amit

After calling the FM , tr this..

IF SY-SUBRC <> 0.

  CALL FUNCTION 'TB_MESSAGE_BUILD_TEXT'
       EXPORTING
            LANGU = SY-LANGU
            MSGID = SY_MSGID
            MSGNO = SY_MSGNO
            MSGV1 = SY_MSGV1
            MSGV2 = SY_MSGV2
            MSGV3 = SY_MSGV3
            MSGV4 = SY_MSGV4
       IMPORTING
            TEXT  = P_L_ERR_MSG.   "  declare this variable of length 100

  write : P_L_ERR_MSG..
ENDIF.

hi,

1) in the FM, only 1 and 2, what if it returns other than 1 and 2? why OTHERS is 2? which means only can cater for 1 and 2 sy-subrc? what if other number then how to take care? or by this way, can restrict system to return only 1 and 2? i know when alright will return 0.

2) why need to call 'tb_message_build_text'?

3) i just do not understand why 'CONVERT_DATE_TO_EXTERNAL' also can return 0 for sy-subrc even i input letter.

please advise again.

thanks
