USER COMMAND will perform actions on radiobutton click

<b>chk this example first using USER-COMMAND USR</b>

REPORT ABC MESSAGE-ID ZZ.

PARAMETERS : IMPORT RADIOBUTTON GROUP RB USER-COMMAND USR,
EXPORT RADIOBUTTON GROUP RB DEFAULT 'X'.

PARAMETERS : P_MATNR LIKE MARA-MATNR.

AT SELECTION-SCREEN OUTPUT.


  IF IMPORT EQ 'X'.
    LOOP AT SCREEN.
      IF SCREEN-NAME EQ 'P_MATNR'.
        SCREEN-INPUT = 0.
        MODIFY SCREEN.
      ENDIF.
    ENDLOOP.
  ELSEIF EXPORT EQ 'X'.
    LOOP AT SCREEN.
      IF SCREEN-NAME EQ 'P_MATNR'.
        SCREEN-INPUT = 1.
        MODIFY SCREEN.
      ENDIF.

hi,

in radio buttons USER-COMMAND can be used to assign a function code fcode to the first parameter in a radio button group. The function code fcode must be specified directly, and have a maximum length of 20 characters. To evaluate the function code, an interface work area of the structure SSCRFIELDS from the ABAP Dictionary must be declared using the statement TABLES. When the user selects any radio button of the radio button group on the selection screen, the runtime environment triggers the event AT SELECTION-SCREEN and transfers the function code fcode to the component ucomm of the interface work area sscrfields.
