Buttons and F3 function key not working in dynpro

[former_member1154847]

I've created a new dynpro which is called from the 1100 dynpro like this:

I've created the Status_1200 and user_command_1200:

PROCESS BEFORE OUTPUT.
  MODULE STATUS_1200.
  MODULE SEL_DATA_1200.

PROCESS AFTER INPUT.
  MODULE USER_COMMAND_1200.

In the 1100 dynpro all the function keys are correct, but when i push the icon to go to the 1200 dynpro, in the new dynpro i need to go back but F3 and cancel button do nothing:

What I'm doing Wrong?

You have add the code in User command module. You can write "Leave to screen 0".

Yes in the USER_COMMAND_1200 I've add this code:

MODULE user_command_1200 INPUT.
  CASE sy-ucomm.
    WHEN '&F03'.
      LEAVE TO SCREEN 0. 
    WHEN '&F15'.
      LEAVE PROGRAM.
    WHEN '$F12'.
      LEAVE SCREEN.
    ENDCASE.
ENDMODULE.

You say "F3 and cancel do nothing", but are you sure that ABAP code in user_command_1200 is not executed? (debug) What code did you define for F3 and cancel to leave screen 1200?

[former_member1154847]

Yes 've added this code in the USER_COMMAND_1200:

MODULE user_command_1200 INPUT.
  CASE sy-ucomm.
    WHEN '&F03'.
      LEAVE TO SCREEN 0. 
    WHEN '&F15'.
      LEAVE PROGRAM.
    WHEN '$F12'.
      LEAVE SCREEN.
    ENDCASE.
ENDMODULE.
