How to make Parameter input field with condition

[Former Member]

Hi Experts,

I have a parameter input field

parameters: p_saknr like skb1-saknr obligatory.

Now i want to give the condition it will accept if skb1-mitkz = 'D'. That time only it will accept the input selection. Otherwise i need a error message.

Plz help this issue.

hiii

you can use it like below code

AT SELECTION-SCREEN OUTPUT
if skb1-mitkz NE 'D'

 LOOP AT SCREEN.
       IF screen-name CS 'P_NUM'.
        screen-input = 0.
        MESSAGE e398
      WITH 'ENTER CORRECT VALUE..'.
        MODIFY SCREEN.
          ENDIF.
ENDLOOP. 
 
 ELSE.
       perform accepted_value_result.

ENDIF..

hi,

In the initialzation event check this condition

if condition is false the raise error message else allow to display screen.

bcoz the initialization event triggers before the screen display.

othrwise you also use the PBO event

i.e AT SELECTION SCREEN OUTPUT.

here check condition

if it is false then raise error message

else all the screen to enter user input

hope this will help you

Hi,

First disable the p_sankr.

if skb1-mitkz = 'D'.

LOOP AT SCREEN.

IF screen-name = 'p_saknr'.

screen-input = 1.

ENDIF.

MODIFY SCREEN.

ENDLOOP.

else.

message w888(sabapdocu) with 'Check your input'.

endif.

Hi,

Try it like this:

At selection-screen on  p_saknr.

   select single  saknr 
      from skb1
      into  w_skb1
   where  saknr  = p_saknr 
      and mitkz  = 'D'.

  check sy-subrc NE 0.
     message 'error....'.

With luck,

Pritam.
