string functions to check if string contains charactets other than digits

[Former Member]

We have a string as an input.

We need to check if it contains any characters other than digits ( ie. 0123456789) The other characters could be special characters, albhabets etc.

Please suggest any RFC / Logic to get this .

IF string CO '0123456789'.

ENDIF.

Suppose string = '1234ABCD'.

Then your logic will give results that the string contains digits/

My requirement is that we have to raise an error if the string contains any thing other than digits.

Please help

string  =   '1234ABCD'.

if string ca '0123456789 '
write 'ok' 
else.
message ' string contains non numeric fields. 
endif.

so trigger the message in the else part .

Eric's solution (CO) works just fine, sniper's (CA) is wrong, at least for your requirement here.

CO = "contains only", CA = "contains any".

P.S. you could also use CN "contains not only" and switch the IF/ELSE-parts around, if you prefer...

It returns that the string contain only digits..please check

[JozsefSzikszai]

if you know the solution better, than why ask at all?

if you get different replies, why don't you try them and see if works or not?

CA stands for contains any

IF string CA '0123456789'

it will be true if the string contains at least one digit

IF string CA '0123456789'
==> the string contains at least one digit
ELSE.
==> the string does NOT contain any digit (however could contain space or special characters)
ENDIF.

CO stands for contains only

IF string CO '0123456789'

it will be true if the string contains only digits

IF string CO '0123456789'
==> the string contains only digits
ELSE.
==> the string contains not only digits (could be no digits at all)
ENDIF.

==> the string contains only

hi,

compare that string with system field sy-abcde..

ex:

data : var type string.

var = '84748291'.
if var CA sy-abcde.
  write : 'Hello'.
else.
  write : 'NO'.
endif.
.
