How to create Option Boxes IN A SELECTION SCREEN.
Thanks!

Answer 1

Hi Rajesh,
The following explanation gives clear picture of what is mean of check box and radio button with coding.....................
<b>CHECK BOX :</b>
AS CHECKBOX [USER-COMMAND fcode]
Effect:
This addition specifies that the input field in the first position of the selection screen is displayed as a checkbox, with the corresponding description next to it on the right. The checkbox is selected if the value of para is "X" or r "x". Otherwise, it is not selected.
The parameter must be created with the type c and length 1. An explicit length len is not permitted. If the addition TYPE is used, this can only be followed by the generic type c or a non-generic data type of type c and length 1.
The addition USER-COMMAND can be used to assign a function code fcode to the parameter. The function code fcode must be directly specified and may 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 the checkbox 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.
Notes
If the TYPE addition is used to make a reference to a data type in the ABAP Dictionary of type CHAR and length 1, and for which t the valid values in the domain are defined as "X" and " ", the parameter is automatically displayed as a checkbox on the selection screen.
If the addition USER-COMMAND is specified without the addition AS CHECKBOX, and the parameter is of type c with length 1, it is also displayed as a checkbox.
The addition USER-COMMAND can, for example, be used for screen modifications with the addition MODIF ID (see example).
<b>Coding :</b>
PARAMETERS show_all AS CHECKBOX USER-COMMAND flag.
SELECTION-SCREEN BEGIN OF BLOCK b1 WITH FRAME.
PARAMETERS: p1(10) TYPE c,
            p2(10) TYPE c,
            p3(10) TYPE c.
SELECTION-SCREEN END OF BLOCK b1.
SELECTION-SCREEN BEGIN OF BLOCK b2 WITH FRAME.
PARAMETERS: p4(10) TYPE c MODIF ID bl2,
            p5(10) TYPE c MODIF ID bl2,
            p6(10) TYPE c MODIF ID bl2.
SELECTION-SCREEN END OF BLOCK b2.
AT SELECTION-SCREEN OUTPUT.
  LOOP AT SCREEN.
    IF show_all <> 'X' AND
       screen-group1 = 'BL2'.
       screen-active = '0'.
    ENDIF.
    MODIFY SCREEN.
  ENDLOOP.
<b>RADIO BUTTON COMMAND :</b>
RADIOBUTTON GROUP group [USER-COMMAND fcode]
Effect:
This addition specifies that the input field is displayed as a radio button in the first position on the selection screen, and the output field is displayed next to it on the right. The radio button is selected if the value of para is "X" or "x". Otherwise, it is not selected.
group is used to define the radio button group for the parameter. The name group is entered directly as a character string with a maximum of 4 characters. Within a selection screen, there must be a minimum of two parameters in the same radio button group. There cannot be more than one radio button group with the same name in one program, even if they are defined in different selection screens.
The parameter must be specified with the type c and length 1. Explicit length specification using len is not permitted. If the addition TYPE is used, it can only be followed by the generic type c or a non-generic data type of type c and length 1.
In a radio button group, only one parameter can be defined with the addition DEFAULT, and the specified value must be "X". By default, the first parameter in a radio button group is set to the value "X", and the rest are set to " ".
The addition 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.
Note:
It is recommended to define the radio buttons of a radio button group directly underneath each other. If the selection screen also contains other elements, it is recommended to define each radio button group within a block surrounded by a frame.
<b>CODING :</b>
tables : mkpf,mseg,ekko.
SELECTION-SCREEN BEGIN OF LINE.
SELECTION-SCREEN BEGIN OF BLOCK B1 WITH FRAME TITLE TEXT-001.
PARAMETER : P_WERKS LIKE MARC-WERKS MODIF ID S1,
            c as checkbox.
SELECT-OPTIONS : S_EBELN FOR EKKO-EBELN NO INTERVALS MODIF ID S2.
SELECTION-SCREEN END OF BLOCK B1.
SELECTION-SCREEN BEGIN OF BLOCK B2 WITH FRAME TITLE TEXT-004.
SELECTION-SCREEN BEGIN OF LINE.
PARAMETERS : R1 RADIOBUTTON GROUP G1 DEFAULT 'X' USER-COMMAND UC1.
SELECTION-SCREEN COMMENT 5(20) TEXT-002 FOR FIELD R1.
SELECTION-SCREEN END OF LINE.
SELECTION-SCREEN BEGIN OF LINE.
PARAMETERS : R2 RADIOBUTTON GROUP G1.
SELECTION-SCREEN COMMENT 5(20) TEXT-003 FOR FIELD R2.
SELECTION-SCREEN END OF LINE.
SELECTION-SCREEN END OF BLOCK B2.
write :/ p_werks,
       / s_ebeln.
AT SELECTION-SCREEN OUTPUT .
LOOP AT SCREEN .
IF R1 EQ 'X' AND SCREEN-GROUP1 EQ 'S2'.
SCREEN-INPUT = 0.
SCREEN-REQUIRED = 1.
clear s_ebeln[].
clear p_werks.
MODIFY SCREEN.
ENDIF.
IF R2 EQ 'X' AND SCREEN-GROUP1 EQ 'S1'.
SCREEN-INPUT = 0.
SCREEN-REQUIRED = 1.
clear s_ebeln[].
clear p_werks.
MODIFY SCREEN.
ENDIF.
ENDLOOP.
Let me knwo if any doubts.
