Validation for Quantity

Hello Gurus,

I am new to XI.....

Currently, I am creating a Web Service that invokes the RFC...RFC posts the Document...

Now, my question :

Is there any means in XI by which we can validate a quantity field ??

I mean if user supplies 'ASDFGGH' in quantity field, it should either give an exception or it should pass as a null value to RFC...

Can I do that in XI??

I know, with custom functions, one can do that...But, it would be great if somebody could explain it...
