String Comparison

Former Member — Tue, 28 Aug 2007 17:32:49 GMT

Hello Experts,

Is there any function module in ABAP to compare the two strings. Let us assume there are 2 string variables STR1 & STR2. If both variables doesn't have the same value then I need an exception.

Thanks in advance.

Hi Mohan,

Is there any specific reason for the use of function module for this small logic?

You can simply compare

IF str1 = str2.

....

ELSE.

RAISE exception.

ENDIF.

Thanks and Best Regards,

Vikas Bittera.

data : str1(20) type c,

str2(20) type c.

str1 = 'Hello'.

str2 = 'Hello1'.

if str1 = str2.

write : 'same'.

endif.

You don't need a function module.

  if str1 <> str2.
     message e001(00) with 'These are not the same'.
  endif.

or....

  if str1 <> str2.
     raise exception < >
  endif.

Hi Mohan,

Also, dont forget to translate to upper case, if you want case insensitive camparison.

TRANSLATE str1 TO UPPERCASE.

Thanks and Best Regards,

Hello,

Thanks for the responses. Yes, the reason for looking the Function Module is, in PPPI Message Recipe we can't compare strings with IF condition. That's why I am trying to find out the standard function module instead of writing custom function module.
