If you want to return to the selection screen, put the error message under AT SELECTION-SCREEN event.


*----------------------------------------------------------------------*
*                      AT SELECTION-SCREEN EVENT                       *
*----------------------------------------------------------------------*

AT SELECTION-SCREEN.

  MOVE sy-ucomm TO sscrfields-ucomm.
  CHECK sscrfields-ucomm EQ 'ONLI'.

* To validate the user input vendor number.
  PERFORM validate_vendor.

*----------------------------------------------------------------------*
*  FORM VALIDATE_VENDOR                                                *
*----------------------------------------------------------------------*
*  Subroutine for validating the user input vendor number.             *
*----------------------------------------------------------------------*
*  There are no interface parameters to be passed to this subroutine.  *
*----------------------------------------------------------------------*
FORM validate_vendor .

  SELECT SINGLE
         lifnr                         " Vendor number
         name1                         " Vendor name
         ort01                         " City
    INTO (w_lifnr,
          w_vend_name,
          w_vend_city)
    FROM lfa1
   WHERE lifnr IN s_lifnr.

  IF sy-subrc NE 0.
    MESSAGE e888(sabapdocu)
       WITH text-nov.
  ENDIF.                               " IF SY-SUBRC NE 0

ENDFORM.                               " VALIDATE_VENDOR

If the user enters the wrong vendor, the error message will be triggered and the user will be returned to the selection screen. If you are in the START-OF-SELECTION event and the processing needs to be stopped immediately, then use a success or information message and write EXIT command. That too will return the selection screen for the user to change the selection-criteria.

use At selection-screen on <field> which would allow to back at the same position.

No, after calling ALV function module, if I get an error message like no data found, I should bring the control back to initial selection screen.

Hi,

Instead putting a error message, you can put a warning message, which makes the user to continue with his program execution after that.

Hi,

you can use leave to transaction.

e.g

AT selection-screen output

IF <CONDITION>

MESSAGE <msg type>.

LEAVE TO TRANSACTION '<tcode>'.

ENDIF.

Before passing the internal table to ALV function module you check whether Any data exists or not if there is not data then simply print a message.

You should be checking if the report output table contains any data or not, even before calling the function module.
