Hi All,

Is there any function module to validate a given value is number or not? (Fm to validate a number).

Thx

Hi senthil,

1. we can use this kind of logic.

2. just copy paste in new program.

It will give X , if number, other wise blank

report abc.

parameters : n(10) type c.

data : flag type c.

perform isnumber using n flag.

write 😕 flag.

*----

form isnumber using str flag.

flag = 'X'.

if str ca sy-abcde.

flag = ''.

endif.

endform.

regards,

amit m.

Hi,

I don't think so, but you can simply check of the variable contains anything else other than 0 to 9. That will tell you if there are non-numeric characters.

Amit's code is not taking care of the special characters.

Hi Senthil.

You can do it this way.

data : numeric_data(10) TYPE c VALUE '0123456789'.

IF infile-order CO numeric_data.

/* Contains only numerals

else.

/* Is alphanumberic.

Endif.

Hi,

A small modification to Amit's code.

PARAMETERS: check(12).

IF check <b>CO '0123456789 '</b>.
  WRITE 'Numbers'.
ELSE.
  WRITE 'Non numeric'.
ENDIF.

Wenceslaus.
