Hi,

Goto Exception Tab

Enter the Exception Name

If u want to raise exception in code.

just write

raise <Exception Name>

Declaring Exception is similar to declaring a simple importing / Exporting Parameter.

Only diffrence is it dont have any type.

In the Exception Tab ; Enter these Values

1) Exception Name

2) Exception Discription.

Hi,

You can create the Exceptions in the Exceptions tab in the Function module,

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.

Hi Chandra,

In the Exceptions tab you have to declare your exceptions and the short text for that exception.In the source code of the FM.You have to raise these exceptions.

Check this example.

CALL FUNCTION 'VIEWPROC_V_T6B1'

EXPORTING

FCODE = FUNCTION

VIEW_ACTION = MAINT_MODE

VIEW_NAME = VIEW_NAME

CORR_NUMBER = CORR_NUMBER

IMPORTING

UPDATE_REQUIRED = STATUS_V_T6B1-UPD_FLAG

TABLES

EXCL_CUA_FUNCT = EXCL_CUA_FUNCT

EXTRACT = V_T6B1_EXTRACT

TOTAL = V_T6B1_TOTAL

X_HEADER = X_HEADER

X_NAMTAB = X_NAMTAB

DBA_SELLIST = DBA_SELLIST

DPL_SELLIST = DPL_SELLIST

CORR_KEYTAB = E071K_TAB

EXCEPTIONS

MISSING_CORR_NUMBER = 1

NO_VALUE_FOR_SUBSET_IDENT = 2

SAVING_CORRECTION_FAILED = 3.

CASE SY-SUBRC.

WHEN 1. RAISE MISSING_CORR_NUMBER.

WHEN 2. RAISE NO_VALUE_FOR_SUBSET_IDENT.

WHEN 3.

ENDCASE.

This FM is called in another Function module that you will create both the exceptions 'RAISE MISSING_CORR_NUMBER' 'RAISE NO_VALUE_FOR_SUBSET_IDENT' with the text you have to declare in your exceptions tab.

execeptions are just nothing but identifiers

which u can use to raise a sensible message to the user other wise it would have dumped on screen

give any name for exception and a description

eg: not_valid : not a valid number

and when ever in the code u want to raise an exception

use statement

raise not_valid.

define all your exceptions, in the function module,

ex : FILE_WRITE_ERROR is the exception i defined in the function module & to call use RAISE

if you want to raise any exception,

use

if sy-subrc <> 0.

RAISE FILE_WRITE_ERROR.

endif.

In the Exceptions tab while creating FM ,

eg: give any name eg : NOT_VALID and its short text as Check not valid

and in the source code

SELECT SINGLE * FROM T005 WHERE LAND1 = COUNTRY.
  IF SY-SUBRC NE 0.
    MESSAGE E001 WITH COUNTRY RAISING <b>NOT_VALID</b>.
  ENDIF.

Lets say we have a FM to fetch material description for a given material number. So one exception can be created as MATERIAL_NOT_FOUND. GO to the exceptions tab in your FM through SE37 and give an exception name MATERIAL_NOT_FOUND.

To raise this exception inside the code use syntax : RAISE MATERIAL_NOT_FOUND.

Hi ,

In FM you will have a tab called exceptions name the exceptions in that place .once that is done go to source code . and write the following thing based on certain condition are something where you like to raise the error.

for this write

if condition.

raise excpetionname.

endif.
