Former Member — Wed, 07 Feb 2007 07:03:10 GMT

In my selection screen i have 1. vbeln as select-options

2. radiobutton1

3. radionbutton2

4. radiobutton3 all these 3 in block.

Now my requirement is when the users enters value in VBELN field and comes out of focus then Radiobuttons has to be disabled.

my problem is i am not getting in which event i have to write the logic

i.e Either he can enter value in VBELN field or select an radiobutton.

AT SELECTION SCREEN. You have to handle this.

Refer this code

Initiate the 'AT selection-screen' EVENT from radiobuttons.

In-order for the Radiobutton selection process to initiate the 'AT selection-screen' event you need to

add the 'USER_COMMAND' option to the parameter declaration. See code below.

*Code used to Initiate the 'AT selection-screen' EVENT from radiobuttons.

selection-screen begin of block group with frame title text-s04.
parameters: p_sel1 type c radiobutton group sel user-command upd.
parameters: p_sel2 type c radiobutton group sel.
parameters: p_sel3 type c radiobutton group sel.
selection-screen end of block group.

or screen-name = 'RADIOBUTTON3' .

if vblen is not initial.

screen-input = '0'.

modify screen.

Enter vbeln number in select options and hit enter .


tables : vbak.

data: dynfields type table of dynpread with header line.

selection-screen begin of block b1 with frame.

select-options : so_vbeln for vbak-vbeln.
PARAMETERS : R1 RADIOBUTTON GROUP RG USER-COMMAND
              R DEFAULT 'X' modif id abc.
PARAMETERS : R2 RADIOBUTTON GROUP RG modif id abc.
PARAMETERS : R3 RADIOBUTTON GROUP RG modif id abc.
selection-screen end of block b1.

at selection-screen output.
if not so_vbeln[] is initial.
LOOP AT SCREEN.
IF screen-group1 = 'ABC' .
screen-input = '0'.
MODIFY SCREEN.
ENDIF.
ENDLOOP.
ENDIF.

//Now my requirement is when the users enters value in VBELN field and comes out of focus then Radiobuttons has to be disabled

what do u mean by out of focus ?

and brief in detial if any more modification is required.

substituting screen-input = '0' for

screen-active = '0' will make the radiobuttons disappear .

u can try this also .

actually i have to write the logic when the cursor is in the selection screen .

i.e after entering values in the Field and press tab (so that cursor comes out of that field) automatically radiobuttons has to be disabled.

hi vijay .

out of focus means after entering values in the Field VBELN when press TAB

cursor comes out of field at that time it has to check whether the Field has value ,

if it has value the it should disable radiobutton..

the thing is 1. i know the logic to disable 2. how to check whether values r there or not.. my main problem is where or which event i have to write this logic.

if i get a solution it will be good.

Hi nagaraju,

1. VBELN field and comes out of focus

In sap gui, (abap) ,

there is no such facility of tracing the

events like ON FOCUS, LOST FOCUS, etc,

which are available in most other programming languages like vb, vc++ etc.

2. Hence, if the user presses TAB,

and the VBELN field is out of focus,

there is no way we can trace this particular out of focus event.
