regarding function

Former Member — Wed, 04 Jul 2007 07:39:28 GMT

Dear Abapers,

I have one doubt about function modules.

while calling function modules in function modules if there is exceptions

how to handle exceptions .I have given one example below.

after exception sy-subrc will come with function module if we put that code is it ok.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

DDIC_STRUCTURE = ' '

retfield =

PVALKEY = ' '
DYNPPROG = ' '
DYNPNR = ' '
DYNPROFIELD = ' '
STEPL = 0
WINDOW_TITLE =
VALUE = ' '
VALUE_ORG = 'C'
MULTIPLE_CHOICE = ' '
DISPLAY = ' '
CALLBACK_PROGRAM = ' '
CALLBACK_FORM = ' '
MARK_TAB =
IMPORTING
USER_RESET =

tables

value_tab =

FIELD_TAB =
RETURN_TAB =
DYNPFLD_MAPPING =

EXCEPTIONS

PARAMETER_ERROR = 1

NO_VALUES_FOUND = 2

OTHERS = 3

IF sy-subrc <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

Hi,

This is correct.

After checking the sy-subrc you can give proper error message based on the exception.

For example.

If sy-subrc = 1.

Display message like "Parameter error"

elseIf sy-subrc = 2.

Display message like "No values found"

elseIf sy-subrc = 3.

Display message like "Other error"

endif.

Reward if helpful.

hi,

All you need to do is have the EXCEPTIONS section uncomment, then simply write out a message depending on the Sy-SUBRC value .

Call function 'Z_TEST_FUNCTION'.

Exceptions

not_found = 1

not_valid = 2

you_are_crazy = 3

you_are_completely_nuts = 4.

case sy-subrc .

when '1'.

write:/ 'Not Found'.

when '2'.

write:/ 'Not Valid''.

when '3'.

write:/ 'You Are Crazy'.

when '4'.

write:/ 'You Are Completely Nuts'.

endcase.

Regards,

Kishi.

Hi,

we can do like this.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

DDIC_STRUCTURE = ' '

retfield =

PVALKEY = ' '
DYNPPROG = ' '
DYNPNR = ' '
DYNPROFIELD = ' '
STEPL = 0
WINDOW_TITLE =
VALUE = ' '
VALUE_ORG = 'C'
MULTIPLE_CHOICE = ' '
DISPLAY = ' '
CALLBACK_PROGRAM = ' '
CALLBACK_FORM = ' '
MARK_TAB =
IMPORTING
USER_RESET =

tables

value_tab =

FIELD_TAB =
RETURN_TAB =
DYNPFLD_MAPPING =

EXCEPTIONS

PARAMETER_ERROR = 1

NO_VALUES_FOUND = 2

OTHERS = 3

<b>IF sy-subrc <> 0.

write:/ 'problem while calling function module.'.

ENDIF. </b>

Exceptions

The exception of a function module are defined on the Exceptions tab page in the Function Builder. Here you can select exception classes to define whether class-based exceptions are declared or non-class-based exception are defined. Class-based exceptions are represented in the above syntax by RAISING, and non-class-based exceptions are represented by EXCEPTIONS.

The addition RAISING is used to declare class-based exceptions that can be propagated from the function module to the caller. Exceptions in the categories CX_STATIC_CHECK and CX_DYNAMIC_CHECK must be explicitly declared, otherwise a propagation can lead to an interface violation. A violation of the interface leads to the treatable exception CX_SY_NO_HANDLER. Exceptions of the category CX_NO_CHECK are implicitly always declared. The declaration of exceptions of the category CX_STATIC_CHECK is statically checked in the syntax check. For exceptions of the category CX_DYNAMIC_CHECK, the check is not performed until runtime. In a function module in which class-based exceptions are declared with the RAISING addition, the statement CATCH SYSTEM-EXCEPTIONS cannot be used. Instead, the relevant treatable exceptions should be handled in a TRY control structure.

The addition EXCEPTIONS is used to define a list of non-class-based exceptions that can be triggered in the function module using the statements RAISE or MESSAGE RAISING. Exceptions defined in this way - as with formal parameters - are bound to the function module and cannot be propagated. If an exception of this type is triggered in a function module, and no return value has been assigned to it with the homonymous addition EXCEPTIONS of the CALL FUNCTION statement when the call was made, this leads to a runtime error.

Note

For new developments after release 6.10, SAP recommends that you work with class-based exceptions that are independent of the function module.

Dear Uma shanker and Kishore,

Thanks for replying me.

this block of statement will come with function module is it ok. but I have writtern in

messge id in Report statement(Report <report-name >) message-id <messge-name>.

IF sy-subrc <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

we have to write explicitely like:-

If sy-subrc = 1.

Display message like "Parameter error"

elseIf sy-subrc = 2.

Display message like "No values found"

elseIf sy-subrc = 3.

Display message like "Other error"

endif.
