using Function code system can identify user interaction to perform the action

usually function code stores in SY-UCOMM system variable

friend for every button there are two things defined

1. text over that button

2. function code

function code is that code which gets copied into sy-ucomm whenever u click that button .

it is used in event AT USER COMMAND. when u want certain action on button click

e.g. case sy-ucomm.

when 'BAK'

<code>

when 'ENTER'

<code>

here BAK & ENTER are function codes of two buttons

plz reward if useful

keep rockin

Function code is attached with any GUI items( like push button or radio button or any menu item) so that we can identify those GUI item events ( such click in the push button) in our program and process accordingly.

Ex:

PROGRAM demo_dynpro_push_button .

DATA: ok_code TYPE sy-ucomm,
      save_ok LIKE ok_code,
      output(8) TYPE c.

CALL SCREEN 100.

MODULE user_command_0100 INPUT.
  save_ok = ok_code.
  CLEAR ok_code.
  CASE save_ok.
    WHEN 'BUTTON_EXIT'.
      LEAVE PROGRAM.
    WHEN 'BUTTON_1'.
      output = 'Button 1'(001).
    WHEN 'BUTTON_2'.
      output = 'Button 2'(002).
    WHEN 'BUTTON_3'.
      output = 'Button 3'(003).
    WHEN 'BUTTON_4'.
      output = 'Button 4'(004).
    WHEN OTHERS.
      output = save_ok.
  ENDCASE.
ENDMODULE.

here various ok-codes 'BUTTON_EXIT' , 'BUTTON_1' ect are attached with the push buttons.

Context menu can be used in relation with the various screen elements

like I/O fields, subscreen,group box,table control but not with push buttons,radio,check buttons.

It can be used to show related options when the user right clicks on the screen elements. It is a type of status. SAP automatically creates a default context menu for dialog statuses consisting of all the function codes available
