Hi all,

I have 2 parameters in selection screen.

Ex:

parameters: p_vkorg like vbak-vkorg,

p_kunnr like vbak-kunnr.

So if the enterd value in p_vkorg does not exist in vbak i want to disable p_kunnr..

How can we do this?

Hi,

You can use the event 'AT SELECTION SCREEN ON OUTPUT'.

And use the propperty of the SCREEN table field INPUT set to 0.

I dont know whether i got you right

normal you do tis validation

At selction-screen on p_vkorg

IF NOT S_PERNR IS INITIAL.

SELECT SINGLE VKORG

FROM VBAK

INTO VBAK-PERNR

WHERE VKORG = P_VKORG.

IF SY-SUBRC NE 0.

MESSAGE E000(ZMESS).

ENDIF.

If you want to validate two fields then put else condition

and write seond v alidation

AT SELECTION_SCREEN OUTPUT.

select single vkorg from <tab1> where vkorg = p_vkorg

if sy-subrc NE 0.

loop at screen.

if screen-name = p_kunnr.

screen-input = '0'.

screen-visible = '0'

modify screen.

endif.

Thanks for replies.

But how you validate the entry for p_vkorg..

<b>We have to validate only in At selection-screen event.</b>

So after validationg how can we disable next paramater?

Hi,

you can use like this..

Parameters p1 as checkbox modif id z1.

at selection-screen output.

loop at screen.

if screen-group1 = 'Z1'.

screen-input = 0.

modify screen.

endloop.

you can check for p_vkorg is exist in vbak or not.. and disable p_kunnr..

Initially you can hide the parameter P_KUNNR and when the user enters a value in P_VKORG, it can be enabled :

parameters: p_vkorg like vbak-vkorg,

p_kunnr like vbak-kunnr.

AT SELECTION-SCREEN OUTPUT.

if p_vkorg is initial.

loop at screen.

if screen-name = 'P_KUNNR'.

screen-input = 0.

modify screen.

endif.

endloop.

else.

loop at screen.

if screen-name = 'P_KUNNR'.

screen-input = 1.

modify screen.

endif.

endloop.

endif.
