Hi,

Create the Dfferent Blocks on the selection screen....depending on the radio button display the corresponing block. For this use Loop at Screen....Endloop in the At Selection-screen Event.

Hi MVPhani,

If u wish to create radio-buttons ( or check-boxes only ) dynamically, then u can achieve the same functionality using the below simpler alternative...

Put a button and while clicking it show the list of possible values ( taken from ur DB table ).. based on the selection display ur report... something like F4 help...

Check the below example..

TYPE-POOLS : slis.

TYPES : BEGIN OF ty_radiobuttons,
        matnr  TYPE matnr,
        maktx  TYPE maktx,
        END  OF ty_radiobuttons.

DATA : lt_radiobuttons TYPE STANDARD TABLE OF ty_radiobuttons,
       ls_radiobutton  TYPE ty_radiobuttons,
       lt_fcat         TYPE slis_t_fieldcat_alv,
       ls_fcat         TYPE LINE OF slis_t_fieldcat_alv.

PARAMETER selvalue TYPE matnr.
SELECTION-SCREEN PUSHBUTTON 60(20) text USER-COMMAND push.

INITIALIZATION.
  MOVE 'Dynamic selection' TO text.

  SELECT matnr
         maktx
    FROM makt UP TO 10 ROWS
    INTO CORRESPONDING FIELDS OF TABLE lt_radiobuttons
   WHERE spras EQ sy-langu.

AT SELECTION-SCREEN .

  CASE sy-ucomm.
    WHEN 'PUSH'.
      PERFORM popup.
    WHEN OTHERS.
  ENDCASE.

START-OF-SELECTION.

END-OF-SELECTION.


*&---------------------------------------------------------------------*
FORM popup.

  DATA : selected_row TYPE slis_selfield,
         action.

  PERFORM build_fcat.

  CALL FUNCTION 'REUSE_ALV_POPUP_TO_SELECT'
    EXPORTING
      i_selection   = 'X'
      i_zebra       = 'X'
      i_tabname     = 'LT_RADIOBUTTONS'
      it_fieldcat   = lt_fcat
    IMPORTING
      es_selfield   = selected_row
      e_exit        = action
    TABLES
      t_outtab      = lt_radiobuttons
    EXCEPTIONS
      program_error = 1
      OTHERS        = 2.

  CHECK sy-subrc EQ 0.
  CHECK action   NE 'X'.
  READ TABLE lt_radiobuttons INTO ls_radiobutton INDEX selected_row-tabindex.
  MOVE ls_radiobutton-matnr TO selvalue.
ENDFORM.                    "popup

*&---------------------------------------------------------------------*
FORM build_fcat.

  FREE lt_fcat.
  ls_fcat-fieldname = 'MATNR'.
  ls_fcat-seltext_l = 'Material'.
  ls_fcat-outputlen = '10'.
  APPEND ls_fcat TO lt_fcat. CLEAR ls_fcat.

  ls_fcat-fieldname = 'MAKTX'.
  ls_fcat-seltext_l = 'Description'.
  ls_fcat-outputlen = '20'.
  APPEND ls_fcat TO lt_fcat.
  CLEAR ls_fcat.
ENDFORM.                    "build_fcat

Cheers,

Jose.
