Identify non-english character in input and show error message.

[former_member604279]

Hi all,
i want to show error message if my input contains any non-english or special characters.
i have tried some function module but it is completely removing it.
instead of removing i want to show error message.

can you please explain how it can be done ?

thanks in advance.

IF (Input field name) NA 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'.
MESSAGE 'Enter ur message' TYPE 'E'.
ENDIF.

I guess you mean CN, not NA.

or preferably, use CO as it should contain only English characters, so NOT to trigger the error:

IF NOT (input field name) CO 'ABCDEF...'.

HI Rishab Mishra,

If you think function module used in your program working correctly in removing special characters other than english letters then write sy-subrc condition below the function module .

function module.
if sy-subrc eq 0.
'Error message'.
 endif.

Could you elaborate on 'English' characters... (ASCII?)

If the FM removed the non-english character (Brexit?) then use a temporary field in the call compare the previous value with the new one, if different, non-english characters removed, then you have your answer?
