How to check the screen input on selection screen smartly?

[Former Member]

Hi all,

I've a selection options plant:

select-option s_werks for marc-werks.

i want to display the error message if user inputs plant = 30xx or 30xx is within the range.

Currently, I use the codes below but i don't think it's smart enough, Is there a smarter way to do so?

AT SELECTION-SCREEN.

loop at s_werks.

if s_werks-sign = 'I'.

case s_werks-option = 'bt'.

...

endcase.

elseif s_werks-sign = 'E'.

case s_werks-option = 'bt'.

...

endcase.

endif.

endloop.

Hi,

Try this.

AT SELECTION-SCREEN.

loop at s_werks.

if ( ( s_werks-sign = 'I' or s_werks-sign = 'E' ).

and ( s_werks-option = 'bt' ) ).

...

endif.

endloop.

Hi Macy,

there might be faster ways than asking the database, but otherwise you will need a lot of coding to check all possible selections.

Try instead:

select werks into l_werks
       up to 1 rows
       from t001w
      where werks in s_werks
       and  werks between '3000' and '3099'.
if sy-subrc eq 0.
  message e398(00) with 'Please don't select 30xx!'.
endif.

So first where clause is from selection-screen, second you can define freely to match your 'forbidden zone' - maybe vlfkz = 'B' (distribution centers) or something else brings same result.

hi Macy,

It is as simple as this...

if '30xx' in s_werks.

<give error msg>

endif.

This will check for the value 30xx as a single value or even if entered as a range.

Hope this helps.

Macy - you can use FM SELECT_OPTIONS_RESTRICT. It's well documented.
