Scope of GET PARAMETER

Hi,

I have created a SET/GET parameter the value of which comes from the user profile in transaction SU3. In the code, using GET PARAMETER, I fetch the value of this parameter into the attribute of a public class and then based on the value in this attribute execute the appropriate code.

I want to know what is the scope of the GET PARAMETER statement. If I am fetching the parameter value using GET PARAMETER and putting it into a class attribute in a particular Function Group, would it be available in other Function Groups also?

Please help.

Thank you.
