Hi,

How are you reading the Data from the application server?

Suppose that you are using a Funcion module call to read the data then

For that function module call you will have some Exceptions listed with a number assigned for each exception.

The function module when called, raises an exception then the number that you assign to that exception will be stored in SY-SUBRC.

SO you need to check SY-SUBRC to see if the function module call is succesful in which case the value of SY-SUBRC will be 0 else it will be the number of the exception that is raised by the Function module.

There are many statements that effect SY-SUBRC, so after a statement if your code has a check for SY-SUBRC then assume that you are checking if the previous statement was sucessful or not.

To see the complete list of commands that effect SY-SUBRC use transaction "ABAPDOCU" and goto "Appendix" there.

Hi,

Then you must be using CALL TRANSACTION and this statement will set SY-SUBRC.

So in you case

CALL TRANSACTION with USING sets SY-SUBRC to 0 if processing was successful, otherwise <>0.

Hope this was helpful

Hi.. Swathi..

To Open a file On Application Server we have the Commands.

We must check the SY-SUBRC to know whether a particular operation is successful.

Eg:

OPEN DATASET V_DSN FOR INPUT IN TEXT MODE ENCODING DEFAULT.

<b>IF SY-SUBRC NE 0. "TO CHECK FILE IS OPENED/EXISTS</b> Message 'File Not Opened' Type 'E'.

Endif.

Do.

Read dataset v_dsn into wa.

<b> IF SY-SUBRC NE 0. "To check END OF FILE</b>

EXIT.

ENDIF.

ENDDO.
