hi,

Check this out

A function module is nothing but a reusable piece of code that can be called from within your code. It takes in some inputs and returns some outputs and probably changes somethings as well. But you want to know when something goes wrong in the code. How will the function module relay that to you? It can send that information as a return parameter(BAPIs and some function modules are examples of this) or it can raise the exceptions that you can trap and do something based on the exception raised. Exceptions are nothing but something unexpected that happened in the function module that is considered as unsuccessful execution of the function module. These exceptions are returned in the form of their integer values. So when you call the function module, you will assign a number to each exception. If that exception is raised in the execution of the function module, then you get a SY-SUBRC value equal to what you set it for. You can then react to it knowing which exception was raised.
