Call screen on button click?

Question

I have a mainscreen with a few buttons in it and I'm trying to assiciate each button with a screen call. I can't get it to work though. I created the button with the layout painter but I don't see how to make it functional.

Any ideas? Thanks!

Answer 1

• open the screen painter
• double click on the button
• enter a Function Code (the field is above "Context Menu Form")

now that your button has a function code it will fire this OK-Code and the dynpros "PROCESS AFTER INPUT" will be run. add a PAI module to the dynpro and in the module you could for example make the following coding:

case sy-ucomm. " the ok code

  when 'your_buttons_function_code_here'.
    call screen YOUR_SCREEN_NUMBER_HERE.

  when others. 
    " DO NOTHING

endcase.

Answer 2

You must create a screen & perform CALL SCREEN inside that event. There's a concept called PAO & PBO. You may refer that too. Few links for your reference..
