selection screen validation

Former Member — Wed, 09 Apr 2008 06:46:08 GMT

Hi all,

I am using the following code for designing the selection screen.

in the following code i am using RB_TAS and RB_POS for radio buttons and S_TASK AND S_OBJID as select options

now if i select RB_TAS then s_objid mist be in display mods and s_task must be visible mode to enter the value. in the same way if i select RB_POS then S_OBJID must be in visible mode so that i can enter some value and same time S_TASK must be in display mode so that not to enter the value.

I must not press enter at any point. if i select the radiobuttons the screen validatiion must happen.

here is the code:

selection-screen begin of block blk1 with frame title text-001.

SELECTION-SCREEN : BEGIN OF LINE.

SELECTION-SCREEN : POSITION 3.

*Radiobutton for task

PARAMETERS : RB_tas RADIOBUTTON GROUP rbg1 DEFAULT 'X' MODIF ID pre.

SELECTION-SCREEN : COMMENT 5(30) text-100 MODIF ID pre.

*Radiobutton for Position.

PARAMETERS : RB_pos RADIOBUTTON GROUP rbg1 MODIF ID pre.

SELECTION-SCREEN : COMMENT 40(12) text-101 MODIF ID pre.

SELECTION-SCREEN : END OF LINE.

SELECTION-SCREEN: SKIP 1.

*&--->selectoptions for task and position

SELECT-OPTIONS: s_task FOR pchdy-objid_str MODIF ID tas,

s_objid FOR pchdy-objid_seq MODIF ID pos.

selection-screen end of block blk1.

how to do the logic in AT SELECTION SCREEN OUTPUT.

CAN ANY BODY SEND THE LOGIC.

NOTE: i must not press enter at any point.

thanks,

giri.

You don't need to add much... try this:


report zlocal_jc_sdn_radio_lock.

tables:
  pchdy.  "Selection Parameters for Database PCH

selection-screen begin of block blk1 with frame title text-001.
selection-screen: begin of line.

selection-screen: position 3.

*Radiobutton for task
parameters :
  rb_tas radiobutton group rbg1 default 'X' modif id pre
    user-command rb1.  "you need this trigger
selection-screen : comment 5(30) text-100 modif id pre.

*Radiobutton for Position.
parameters :
  rb_pos radiobutton group rbg1 modif id pre.
selection-screen : comment 40(12) text-101 modif id pre.

selection-screen : end of line.

selection-screen: skip 1.
*&--->selectoptions for task and position
select-options:
  s_task                for pchdy-objid_str modif id tas,
  s_objid               for pchdy-objid_seq modif id pos.
selection-screen end of block blk1.

at selection-screen output.
  perform at_selection_screen_output.  "lock screen fields before display

*&---------------------------------------------------------------------*
*&      Form  at_selection_screen_output
*&---------------------------------------------------------------------*
form at_selection_screen_output.

  loop at screen.
    if  screen-name cs 'S_TASK'
    and rb_tas is initial.
      screen-input = '0'.
    endif.
    if screen-name cs 'S_OBJID'
    and rb_pos is initial.
      screen-input = '0'.
    endif.
    modify screen.
  endloop.

endform.                    "at_selection_screen_output

Add User Command to radiobutton declaration statement for RB_TAS and write the logic in at selection-screen output
