Screen navigation

jepi_flanders — Fri, 02 Mar 2012 05:34:41 GMT

Dear Experts,

I'm new to Abap and have a question concerning screen navigation: in my program I have a selection screen 0100 (created with SELECTION-SCREEN BEGIN OF SCREEN 100...., and called with CALL SELECTION-SCREEN 100) then, when pressing Execute (F8) the logics works and present the result via WRITE statements.

Up to here, no problems.

Now I would like that, when I press 'Back' (F3), I'm returning to the selection screen, for new selections. Instead, if I press 'Back' I'm going really back to the SE38 transaction, for instance, and then I need to run the program again to have a new selection.

This is maybe a basic question, but I already searched on the internet without success, and I'm really frustrated not being able to find a solution to this.

Hope you can help me.

Best regards,

Jepi

In your PF status for 'BACK' do


case sy-ucomm.
when 'back'.
   leave to screen 0.

Hi,

Create a module with AT-EXIT COMMAND.


CASE SY-UCOMM.
  WHEN 'BACK'.
    LEAVE TO SCREEN 100.
ENDCASE.

Danish.

Hi,

By writing "leave to screen 0100." will help you solve this problem.

Hope this helps.

Well since it is an executable program i guess you cannot use GUI statuses or Exit module. Well normally if you hit the back button it should return to the program. may be some small logic error in your program if you can post your program here we could check.

Dear all,

Thank you for replying.

@ Danish: Could you please tell me where shall I create the module?

Do I have to create a new screen, say 200, and there write the result from the program, and in its flow logic add the module with AT-EXIT COMMAND?

Thanks again.

Hi Kalyan,

Thank you for answering.

In reality, the screen 100 flow logic is automatically created and has already a MODULE %_BACK AT EXIT-COMMAND.

Maybe, have I to create a new screen, say 200, and there put my new flow logic?

Thanks again

Hi,

I think you no need to create another screen.

You can clear the field as you click on BACK button after displaying your results, is that ok for you?



      WHEN 'BACK'.
        LEAVE TO  SCREEN 100.
        cx_input  = ''. " if a checkbox is there
        CLEAR i_input." clear input field as i_input is input field for you

For Selection Screen you need not call screen as 100 and all( default screen 1000 is present ) , We can use it by declaring parameters , select-options etc directly .If u have to manipulate Selection screen then u can use Selection Screen EVENTS for more screen navigation and calculations.

If you are using multiple selection screens then set navigation using event

At selection-screen output.

set pf-status '100'. "Set fcode for back button as 'BACK'.

at selection-screen

CASE sscrfields-ucomm.

WHEN 'BACK'.

LEAVE PROGRAM.
