[Former Member]

Hi friends

iam working on events in reports.

with at selection-screen output iam doing screen validations(loop at screen).

my requirement is : i have checkboxes ,. if c_or = 'x' i want to dispaly 2 select-options for input .

after that start-of-selection and fieldcats are there.

but my problem was iam not getting output its only diaplaying empty list.

i had done debugging also ( on at selection-screen output) but the cursor comes out and dipslyaing empty list.

can anybody chosee the way ....

Your question is a little confusing... your code should be structured something like:

parameters:
  p_parm1     as checkbox.
select-options:
  s_bukrs     for t001-bukrs.

at selection-screen output.
" this occurs before the screen display and is where you adjust the layout eg hide or lock fields
  perform at_selection_screen_output.

at selection-screen.
" this occurs after the user hits enter or executes the report - put validations here
  perform at_selection_screen.

start-of-selection.
" Now we can use the parameters to get info from database into internal tables etc
  perform get_data.

end-of-selection.
" Data have been collected so show it to the user...
  perform output_data.

Check for input u r providing.

If u want 2 select-options to display u must group them using MODIF ID.

Hi, Satya,

Suposse you have two fields on SELECTION-SCREEN:

SELECT-OPTIONS :

s_field1 FOR mara-matnr MODIF ID sg1,
s_field2 FOR mara-matnr MODIF ID sg2,

s_field3 FOR vbak-vbeln.

PARAMETER : p_test AS CHECKBOX DEFAULT 'X' USER-COMMAND uc1.

Note: it's VERY important to have USER COMMAND on the checkbox, because it triggers the whole event.

To hide or diplay a field with a checkbox, you must do LOOP AT SCREEN, on AT SELECTION-SCREEN OUTPUT event:

 
AT SELECTION-SCREEN OUTPUT.

LOOP AT SCREEN.
*** If checkbox is marked, shows fields:
  IF p_test IS NOT INITIAL.
    IF screen-group1     = 'SG1' OR
       screen-group1     = 'SG2'.
       screen-active     = 1.
    ENDIF.

  ELSE.
*** If checkbox is NOT marked, hides fields:
    IF screen-group1     = 'SG1' OR
       screen-group1     = 'SG2'.
       screen-active     = 0.
    ENDIF.
  ENDIF.

*** Important!!! Makes screen changes visible:
MODIFY SCREEN.
ENDLOOP.

AT SELECTION-SCREEN OUTPUT.

LOOP AT SCREEN.

IF screen-name = 'P_FILE' or Screen-name = 'P_FILE1'.

IF p_dl = 'X'.

screen-input = '1'.

MODIFY SCREEN.

ELSE.

screen-input = '0'.

MODIFY SCREEN.

ENDIF.

ENDIF.

ENDLOOP.

Write : p_file,p_file1.

hope this will solve your problem.
