Hi leeza,

1. Using OBLIGATORY

at the time of parameters definition

won't help.

2. Hence, we need to

EXPLICITLY

use IF-ENDIF

and check parameter is INITIAL.

3. So if smoething is found wrong,

then

message s999(yhr) with 'Field is compulsory'.

LEAVE LIST-PROCESSING. <---- IMPORTANT.

hi leeza,

check this sample..

clicking on check1 makes the select-options mandatory..

tables : vbap.

data : vbap_wa like vbap.

PARAMETERS : CHECK radiobutton group rd1 user-command chk ,

check_1 radiobutton group rd1 .

select-options : s_vbeln for vbap-vbeln MODIF ID B .

at selection-screen on radiobutton group rd1.

LOOP AT SCREEN.

IF CHECK NE 'X' AND SCREEN-GROUP1 = 'B'.

SCREEN-required = '1'.

ENDIF.

modify screen.

ENDLOOP.

Hi,

You can do this via the event "AT SELECTION SCREEN".



SELECTION-SCREEN BEGIN OF BLOCK a1.
 SELECTION-SCREEN BEGIN OF BLOCK b1 WITH FRAME TITLE text-001.
  PARAMETERS r_write RADIOBUTTON GROUP radi MODIF ID aa
            USER-COMMAND abc DEFAULT 'X'.
  PARAMETERS r_rever  RADIOBUTTON GROUP radi MODIF ID aa.

  SELECTION-SCREEN END OF BLOCK b1.

  SELECTION-SCREEN BEGIN OF BLOCK b2 WITH FRAME TITLE 
                                            text-002.

  PARAMETERS p_start LIKE sy-datum MODIF ID bb.
  PARAMETERS p_date  LIKE sy-datum MODIF ID cc.  
  PARAMETERS p_rever LIKE sy-datum MODIF ID dd.  

  SELECTION-SCREEN END OF BLOCK b2.

  SELECTION-SCREEN END OF BLOCK a1.

AT SELECTION-SCREEN OUTPUT.
  IF r_write EQ gc_mark.
    gv_block = 'DD'.
    PERFORM f6000_deactivate.

  ELSEIF r_rever EQ gc_mark.
    gv_block = 'CC'.
    PERFORM f6000_deactivate.
  ENDIF.

FORM f6000_deactivate.

  LOOP AT SCREEN.
    screen-active = '1'.
    IF screen-group1 = gv_block.
      screen-active = '0'.
    ENDIF.
    MODIFY SCREEN.
  ENDLOOP.

ENDFORM.

Hey Leeza, if you want the field to be mandatory, just add the keyword OBLIGATORY next to it while decalring, so that the field becomes mandatoty.

I hope this is suffice. If any doubt just message.

Thanks & Regards,
