Screen flow not working

Former Member — Mon, 09 Mar 2009 05:26:18 GMT

Hi Experts,

I have a screen 9000 from which I want to display a "list output". I have set a pf-status for 9000.

In PAI of 9000 I written like

leave TO LIST-PROCESSING AND RETURN TO SCREEN 9000.

write : / 'hai'.

leave screen.

The list output comes correctly, but when I press Back button it didn't go to 9000 screen. Moreover in the status bar I am able to see the fuction code of 9000's Back button. But 9000's PAI also don't get triggered. How can I handle this situation. Can I handle user command of list processing screen.

Thanks and regards,

Venkat.

As per your requirement follow code:-

In PAI:-


LEAVE TO LIST-PROCESSING.
WRITE : / 'HELLO'.
"other write statements......

Now in PAI, include code when user click BACK button:-


MODULE user_command.
  CASE sy-ucomm.
    WHEN 'BACK'.
      SET SCREEN '9000'.
      LEAVE SCREEN.
  ENDCASE.
ENDMODULE.

Hope this helps you.

Hi Venkat

try this code.

In this you need to call a screen 100 that contains a PUSH BUTTON with fcode 'PUSH'.

When you push this button it will trigger LEAVE TO LIST-PROCESSING.

Now the list is displayed.If you press back on thes list it will take you bavk to screen 100.

REPORT  zscreen.
CALL SCREEN 100.
*&---------------------------------------------------------------------*
*&      Module  STATUS_0100  OUTPUT
*&---------------------------------------------------------------------*
*       text
*----------------------------------------------------------------------*
MODULE status_0100 OUTPUT.
  SET PF-STATUS 'SCREEN'.
*  SET TITLEBAR 'xxx'.

ENDMODULE.                 " STATUS_0100  OUTPUT
*&---------------------------------------------------------------------*
*&      Module  USER_COMMAND_0100  INPUT
*&---------------------------------------------------------------------*
*       text
*----------------------------------------------------------------------*
MODULE user_command_0100 INPUT.
  CASE sy-ucomm.
    WHEN 'PUSH'.
      LEAVE TO LIST-PROCESSING .
      WRITE : / 'hai'.

         WHEN 'BACK'.
      LEAVE TO SCREEN 100.
  ENDCASE.
ENDMODULE.                 " USER_COMMAND_0100  INPUT

Hope this will help you.

You haven't wrote anything in your code to handle the back functionality. So, you need to create a Case for your Back button as well. As specified by Hareesh, I think in your case:


When 'PUSH'.
Leave to screen 0.    "this will bring you to your first screen
