HOW TO RAISE EXCEPTION IN FUNCTION MODULE !

I have created a function module....where i want to raise some error message when some wrong data will be inputed
what is the syntax ? Please tell me the syntax .

hi you can do like this:
in exception tab of FM write exceptions you want to raise.
e.g. incorrect_input.
now in code write

How to create EXCEPTION in function module

hi,
Raising Exceptions
There are two ABAP statements for raising exceptions. They can only be used in function modules:
RAISE except.
und
MESSAGE.....RAISING except.
The effect of these statements depends on whether the calling program handles the exception or not. The calling program handles an exception If the name of the except exception or OTHERS is specified after the EXCEPTION option of the CALL FUNCTION statement.
If the calling program does not handle the exception
·         The RAISEstatement terminates the program and switches to debugging mode.
·         The MESSAGE..... RAISING statement displays the specified message. Processing is continued in relation to the message type.
If the calling program handles the exception, both statements return control to the program. No values are transferred. The MESSAGE..... RAISING statement does not display a message. Instead, it fills the system fields sy-msgid, sy-msgty, sy-msgno , and SY-MSGV1 to SY-MSGV4.
Source Code of READ_SPFLI_INTO_TABLE
The entire source code of READ_SPFLI_INTO_TABLE looks like this:
FUNCTION read_spfli_into_table.
""Local Interface:
*"       IMPORTING
*"             VALUE(ID) LIKE SPFLI-CARRID DEFAULT 'LH '
*"       EXPORTING
*"             VALUE(ITAB) TYPE SPFLI_TAB
*"       EXCEPTIONS
*"              NOT_FOUND
SELECT * FROM spfli INTO TABLE itab WHERE carrid = id.
IF sy-subrc NE 0.
    MESSAGE e007(at) RAISING not_found.
ENDIF.
ENDFUNCTION.
The function module reads all of the data from the database table SPFLI where the key field CARRID is equal to the import parameter ID and places the entries that it finds into the internal table spfli_tab. If it cannot find any entries, the exception NOT_FOUND is triggered with MESSAGE ... RAISING. Otherwise, the table is passed to the caller as an exporting parameter.
Calling READ_SPFLI_INTO_TABLE
The following program calls the function module READ_SPFLI_INTO_TABLE:
REPORT demo_mod_tech_fb_read_spfli.
PARAMETERS carrier TYPE s_carr_id.
DATA: jtab TYPE spfli_tab,
      wa   LIKE LINE OF jtab.
CALL FUNCTION 'READ_SPFLI_INTO_TABLE'
     EXPORTING
          id        = carrier
     IMPORTING
          itab      = jtab
     EXCEPTIONS
          not_found = 1
          OTHERS    = 2.
CASE sy-subrc.
WHEN 1.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno.
WHEN 2.
    MESSAGE e702(at).
ENDCASE.
LOOP AT jtab INTO wa.
WRITE: / wa-carrid, wa-connid, wa-cityfrom, wa-cityto.
ENDLOOP.
The actual parameters carrier and jtab have the same data types as their corresponding interface parameters in the function module. The exception NOT_FOUND is handled in the program. It displays the same message that the function module would have displayed had it handled the error.
Hope this is helps,Do reward.

Raise exception in function module call from SAP owned program

I need to raise an exception in a function module to terminate a transaction, display a error message and return to to previous selection screen so the user can fix the error before moving forward.......
How do you do this when the program using the function module is SAP owned?
Thank You!
Jeff

Hi,
After calling the function module, you can do something like this.
IF SY-SUBRC <> 0.
RAISE EXCEPTION.
ENDIF.

Raising exceptions in function module

I am writing a coding inside the userexit. The call customer function has 'exception' parameters like below:
         EXCEPTIONS
           IDOC_ERROR          = 1
           DO_NOT_PROCESS_IDOC = 2
           OTHERS              = 3.
Now, I want to raise the exception to '1' depending on some conditions. How do I do that? I used to just get the import parameters from the funciton module but never raised exceptiosn before.
please advice.
Thanks

Hi,
Please try this.
IF <your field check> NE <your condition>
RAISE IDOC_ERROR.
ENDIF.
OR
SY-SUBRC = '1'.

Exception in Function Module

Hi,
How to use exception in Function module ?
How Can I use the exception my program while calling the Function Module ?
Can anyone explain with example ?
Thanks
NK

HI,
if something happens in ur FM and u want it to be tracked in ur calling program, then u can use exception...............
If u r having(say) 3 exceptions in ur FM....
and in ur calling program its like below.
EXCEPTIONS
exception1 = 1
exception2 = 2
exception3 = 3
then if the first exception is raised in ur FM,then sy-subrc value ll be 1( exception1 = 1 )....llly if the second exception is raised in ur FM,then sy-subrc value ll be 2( exception2 = 2 ).........
now u can use this sy-subrc values like below....
If sy-subrc = '1'.
message 'First exception is raised' type 'I'.
else.
message '2nd or 3rd exception is raised' type 'I'.
endif.

Hi,
if that condition is not satisfied,and u didn't handle that exception while calling function module then in the runtime error u will get the text as the description of the exception in function module definition.

Or
just have to decide what exceptions u want and under what conditions.
then declarethese exeptions under the exceptions tab.
in the source code of ur function module.
if
like this u can code .
now when u call the function module in tme mainprogram.
if some error occurs and u have declared a exception for this then it will set sy-subrc = value u give inthe call of this fm.
in the fm u can program these sy-subrc values and trigger the code for ur exception.

How to catch excpetions of function module?

Hallo everybody,
how can i catch the exception from function module "exception" and deliver it to call function parameter table --exception table.
For example,a function module 'RPY_TABLE_INSERT' is called by Call Function (parameter_table)in order to create a new table.When the table exists already, a exception "Already_exist" activated.But it can not be caught,since it is raised by "message raise". Therefore in the exception-table of caller no error is caught.
How can I deal with it?
Thanks in advance!
Message was edited by: Liying Wang

CALL FUNCTION 'RPY_TABLE_INSERT'
EXPORTING
LANGUAGE                = SY-LANGU
    TABLE_NAME              =
WITH_DOCU               = ' '
DOCUTYPE                = 'T'
TRANSPORT_NUMBER        = ' '

    TABL_INF                =

PERMISSION_ERROR        = 3
NAME_NOT_ALLOWED        = 4
NAME_CONFLICT           = 5
DB_ACCESS_ERROR         = 6
OTHERS                  = 7
IF SY-SUBRC <> 0.
as per the error sy-subrc will be set, you can see in the exceptions ( 1 for cancel, 2 for already exit)
so using this subrc you can determine the error

Raising Exceptions
There are two ABAP statements for raising exceptions. They can only be used in function modules:
RAISE <except>.
and
MESSAGE..... RAISING <except>.
The effect of these statements depends on whether the calling program handles the exception or not. If the name <except> of the exception or OTHERS occurs in the EXCEPTIONS addition of the CALL FUNCTION statement, the exception is handled by the calling program.
If the calling program does not handle the exception
The RAISE statement terminates the program and switches to debugging mode.
The MESSAGE ..... RAISING statement display the specified message. How the processing continues depends on the message type.
If the calling program handles the exception, both statements return control to the program. No values are transferred. The MESSAGE ..... RAISING statement does not display a message. Instead, it fills the system fields SY-MSGID, SY-MSGTY, SY-MSGNO, and SY-MSGV1 to SY-MSGV4.
Source Code of READ_SPFLI_INTO_TABLE
The entire source code of READ_SPFLI_INTO_TABLE looks like this:
FUNCTION READ_SPFLI_INTO_TABLE.
""Local interface:
*"       IMPORTING
*"             VALUE(ID) LIKE SPFLI-CARRID DEFAULT 'LH '
*"       EXPORTING

SELECT * FROM SPFLI INTO TABLE ITAB WHERE CARRID = ID.
IF SY-SUBRC NE 0.
    MESSAGE E007(AT) RAISING NOT_FOUND.
ENDIF.
ENDFUNCTION.
The function module reads all of the data from the database table SPFLI where the key field CARRID is equal to the import parameter ID and places the entries that it finds into the internal table SPFLI_TAB. If it cannot find any entries, the exception NOT_FOUND is triggered using MESSAGE...RAISING. Otherwise, the table is passed to the caller as an exporting parameter.

Exceptions in function module

Hi,
What are the exceptions in function module.
Thanks in advance

HI,
Exceptions are used to return the error which happens in function module to the calling program.
You can't show error messages directly from Function modules. So when there are some error occurs in function module it raises the desired exception. and this exception number is passed back to calling program. in this way calling program can trace out the error happens in function module.
REgards,

What is the Exceptions in function module

Hi,
wt is the exceptions in function module? can anyone tell me?
Thanks
swathi

Exception is the mechanism by which you can give the error messages back to the program.
Say for the REUSE_ALV_GRID_DISPLAY, we have so many exceptions. Every exception has some meaning. Say the exception PROGRAM_NOT_FOUND will be raised when you had passed wrong program name in the CALLBACK program.
PROGRAM_NOT_FOUND = 1...
If the exception was raised than this value will be set to the SY-SUBRC.
SO, by accessing SY-SUBRC, you can get to know which exception was raised.

Hi,
You can use the function module RS_FUNCTION_DELETE to do that.
Make sure you are not deleting any standard FM's.
Example
      call function 'RS_FUNCTION_DELETE'
           exporting
                funcname          = 'ZFM_NAME" " Function modue name
                suppress_popups   = 'X' " TO suppress any pop-ups that come when you delete
           exceptions
                error_message     = 1
                cancelled         = 2
                function_released = 3
                others            = 4.
