classical selection screen

Former Member — Wed, 05 Aug 2009 14:18:34 GMT

Hi colleagues,

I call a classical selection screen. At the bottom there are several buttons like OK, CANCEL etc. Unfortunately I can not reach the event when pressing the cancel button. I use AT SELECTION SCREEN but the system does not stop. With the OK button it works..

Has anybody an idea?

TAHNKS!!

Maybe you haven't mentioned the code for cancel.

Say you have the function code for cancel button is "CANCEL" then in the user command of PAI module of your screen you will have to write this:

CASE SY-UCOMM.

WHEN 'CANCEL'.

LEAVE TO SCREEN 0.

Mention your own screen here on which you want to be after clicking the cancel button.

ENDCASE.

also write the code for OK button so as to move forward on next screen.
you can also use above buttons of (EXIT,CANCEL,BACK)
then you should write in WHEN 'EXIT' OR 'CANCEL' OR 'BACK'.

Regards,

Lucky

this code might help you

AT USER-COMMAND.
  IF flag = 'X'.
    CASE sy-ucomm.
      WHEN 'EXIT' OR  'BACK' OR 'CALC'.
        LEAVE TO SCREEN 0.
    ENDCASE.
    EXIT.
  ENDIF.
  CASE sy-ucomm.
    WHEN 'SALEORDER'.
      DO.
        READ LINE sy-index LINE VALUE INTO list_line.
        IF sy-subrc NE 0.
          EXIT.
        ENDIF.
        IF list_line(1) EQ 'X'.
          v_vgbel = sy-lisel+91(10).
          v_vgpos = sy-lisel+102(6).
          READ TABLE lt_final INTO wa_final WITH KEY vgbel = v_vgbel
                                                     vgpos = v_vgpos.
          IF sy-subrc = 0.
            wa_final-box = 'X' .
            MODIFY lt_final FROM wa_final  INDEX sy-tabix TRANSPORTING box.
          ENDIF.
          CLEAR wa_final.
        ENDIF.
      ENDDO.
      PERFORM bcd_vk11.

Try this.

   CASE ok_code.
    WHEN 'F_EXIT'.
      LEAVE PROGRAM.
    WHEN 'F_CANCEL'.
      LEAVE TO SCREEN <screen_number>.
  ENDCASE.
ENDMODULE.

Thanks,

Try setting a PF-STATUS

use the EVENTS at user-command or at pf-status

for more info go through the ABAPDOCU examples

Hi guys,

thank you very much for your prompt inputs. It turned out that a selection screen within a selection screen is nevertheless a bad solution. The behaviour described above may also be correct as "cancel" in this context simply means: do nothing and exit.

My problem is solved.

THANKS!!
