Hi Bhanu,

Return codes are the SY-SUBRC values set by a funtion module when you raise an exception. Say you have created 5 exceptions for a function module, then the first function module if raised using RAISE <exception> command would set SY-SUBRC as 1 in the calling program ... and so on.

It is mainly used for exception/error handling.

E.g. You have a function module with exceptions

EXCEPTION1

EXCEPTION2

When you call the function module in calling program using Pattern, it would create the following code:

EXCEPTIONS

EXCEPTIONS1 = 1

EXCEPTIONS2 = 2.

Aditya

The exporting section of the interface is used to communicate the results of the ABAP handler processing. The return code RFCRC parameter is a single field used to determine the code a connector returns. The possible values are:

RC = 0 (success, VALCHANGE)

RC = 1 (failure, FAIL)

The RETURN_TEXT parameter is a 120-character free text field that is written to by the connector or logged as an error message in the return status descriptor. If the ABAP handler does not provide a value for this parameter, then Y_XR_RFC_DO_VERB_NEXTGEN supplies default text depending on the return code.

Note:

The exceptions section of the interface defines two exceptions. It is recommended that you use the exporting parameters instead.

Hi,

Inorder to get return codes u have to maintain exceptions in the function module and u have to raise that exception in the function module then only when u call the FM in ur program the sy-subrc value is returned other wise it will always return as ZERO..

this is the way u have to do..

source code in FM..

import

MATNR TYPE MATNR

export

....

tables

...

exceptions

NO_DATA

select matnr from mara where matnr = matnr.

if sy-subrc ne 0.

RAISE NO_DATA.

endif.

ENDFUCNTION.

now when u call this FM in ur program

CALL FUNCTION <FMNAME>

EXPORT

MATNR = MATNR

EXCEPTIONS

NO_DATA = 1.

if sy-subrc ne 0.

throw error message.

endif.
