Best practice to make the sy-ucomm to be fcode.
leave to screen 0. <--- to exit the current screen
leave program. <---- to exit the whole rogram
*** normally the program created in module pool (not executable) execute via TRANSACTION CODE
PROGRAM ZBC400_22_SCREEN.
DATA : FCODE TYPE SY-UCOMM.
tables : sflight.
*&---------------------------------------------------------------------*
*& Module SET_GUI_AND_TITLE OUTPUT
*&---------------------------------------------------------------------*
* text
*----------------------------------------------------------------------*
MODULE SET_GUI_AND_TITLE OUTPUT.
set PF-STATUS 'GUI100'.
set TITLEBAR 'TITLE' with sy-uname.
ENDMODULE. " SET_GUI_AND_TITLE OUTPUT
*&---------------------------------------------------------------------*
*& Module PROCESS_F_CODE INPUT
*&---------------------------------------------------------------------*

MODULE PROCESS_F_CODE INPUT.
CASE FCODE.
when 'ENTER'.
select single *
from sflight
WHERE carrid = sflight-carrid
and connid = sflight-connid
and fldate = sflight-fldate.
call screen 200.
WHEN 'GO_BACK'.
IF sy-dynnr = 200.
LEAVE to SCREEN 0.
else.
leave PROGRAM.
ENDIF.
WHEN 'SPECIAL'.
MESSAGE i010(ad) with 'special report'.
WHEN OTHERS.
ENDCASE.
ENDMODULE. " PROCESS_F_CODE INPUT
DIAGRAM 3.0
Based on the above data.
1. create a program (module pool)
2. create screen100 *try not to use 1000 above cause it is standard
PROCESS BEFORE OUTPUT.
MODULE set_gui_and_title.
* MODULE STATUS_0100.
*
PROCESS AFTER INPUT.
-- remember to use the Fcode in element list
3. create gui_status <--- this is for the screen
DIAGRAM 4.0
with this you can create icon and remember th fcode you can use the variable you created too
As for the application tool bar you can add your own ICON!! and apply the same FCODE too
Last but not least dont forget to create the title
DIAGRAM 5.0
**** CLICK on SCREEN then LAYOUT
here you can create your layout
remember for function aka push button remember to put the function code so that your system can manipulate it
remember what ever RED in colour when editing during layout its meaning is more towards error.
REMEMBER TO CALL YOUR PBO AND PAI MODULE INSIDE THE SCREEN!!! EXAMPLE DIAGRAM 3.0
* notice that we are all working in se80 that is why you can see the layout besides
* remember the coding above is sufficient for normal usage.
