One suggestion is:

You can make the download file field non-editable..i mean, gray out the field first. And when download is selectes you can make it editable. This is possible by :

LOOP AT SCREEN.

IF screen-name = 'XYZ'.

screen-input = 0.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

Just try this once..

Hi Dude,

For screen fields handling we have a structure called SCREEN..by using this structure we have to handle this...



parameters: ps_parm as listbox visible length 10
                          user-command abc.
* Radio buttons
parameters: rb1 radiobutton group ab modif id bl2,
            rb2 radiobutton group ab modif id bl2,
            rb3 radiobutton group ab modif id bl3.

initialization.

* Populate list box values
  name = 'PS_PARM'.
  value-key = '1'. value-text = 'Line 1'. append value to list.
  value-key = '2'. value-text = 'Line 2'. append value to list.

  at selection-screen output.

* Set list box with value
  call function 'VRM_SET_VALUES'
    exporting
      id     = name
      values = list.
* Control the display of screen components
  loop at screen.
    if ps_parm = 1.
      if screen-name = 'RB1' or screen-name = 'RB2' .
        screen-invisible = 0.
      elseif screen-name = 'RB3'.
        screen-invisible = 1.
      endif.
      modify screen.
    elseif ps_parm = 2.      if screen-name = 'RB1' or screen-name = 'RB2' .
        screen-invisible = 1.
      elseif screen-name = 'RB3'.
        screen-invisible = 0.
      endif.
      modify screen.
    elseif ps_parm = space.
      rb1 = 'X'.
      clear: rb2,rb3.
      if screen-name = 'RB1' or screen-name = 'RB2' or
         screen-name = 'RB3'.        screen-invisible = 0.
        modify screen.
      endif.
    endif.  endloop.

 at selection-screen.
  if sscrfields-ucomm = 'ABC'.  endif.

  start-of-selection.

  write: / 'Parameter:', ps_parm.

Write the following code in at selecection-screen output:

If download = 'X'.

loop at screen.

screen-name = 'X'.

screen-input = 0.(screen-input has two options 0 and 1 : 0=no-display, 1= display)

modify screen.

endloop.

endif.

Hope this solve issue

Hi,

You can write the below logic.

PARAMETERS: rb_file RADIOBUTTON GROUP g1,
            rb_other RADIOBUTTON GROUP g1.
PARAMETERS: p_file TYPE char50.

AT SELECTION-SCREEN ON RADIOBUTTON GROUP g1.
  LOOP AT SCREEN.
    IF screen-name = 'P_FILE'.
      IF rb_file EQ 'X'.
        screen-required = 1.
        MODIFY SCREEN.
      ELSE.
        screen-required = 0.
        MODIFY SCREEN.
      ENDIF.
    ENDIF.
  ENDLOOP.

Hi,

If you take a radiobutton then it will be checked by default (if only one radiobutton is present on screen).

So make sure that you have more than one radiobuttons on screen

Follow this code:-


PARAMETERS : p_filename TYPE rlgrap-filename MODIF ID abc. " download file name parameter
PARAMETERS : p_rb1 RADIOBUTTON GROUP gp1, "for file download
             p_rb2 RADIOBUTTON GROUP gp1. "for other purpose

AT SELECTION-SCREEN OUTPUT.
  IF p_rb1 = 'X'.
    LOOP AT SCREEN.
      IF screen-group1 = 'ABC'. "for textbox (file download parameter)
        screen-required = 1. "make screen mandatory
      ENDIF.
      MODIFY SCREEN.
    ENDLOOP.
  ELSE.
    LOOP AT SCREEN.
      IF screen-group1 = 'ABC'. "for textbox (file download parameter)
        screen-required = 0. "make screen not-mandatory
      ENDIF.
      MODIFY SCREEN.
    ENDLOOP.
  ENDIF.

Hope this helps you.

Hi,

Then try this way:-


PARAMETERS : p_filename TYPE rlgrap-filename. " download file name parameter
PARAMETERS : p_rb1 RADIOBUTTON GROUP gp1 USER COMMAND abc, "for file download
             p_rb2 RADIOBUTTON GROUP gp1 DEFAULT 'X'. "for other purpose
 
AT SELECTION-SCREEN.
  IF p_rb1 = 'X'.
    IF p_filename IS INITIAL.
      MESSAGE 'specify file name' TYPE 'E'.
    ENDIF.
  ENDIF.

Hope this solves your problem.
