Hi,

Import - parameters that are used to pass data to a function module.  
Export - parameters that are used to receive data from a function module 
Changing - parameters that are used both to pass data to and receive data from a function module.  
Tables - tables that are to be passed to a function module.  
Exceptions - Errors/Exceptions raised during fucntion module calls.

hi saurav..

these terms are relative in terms of FM side and Calling environment side.

see.. from calling environment (eg:report program) point of view:

export means what u pass to FM
import means what you get from FM.

but from FM point of view

import means what you get into the FM ---- = export from program point of view.
export means what you send out from FM ---- = import  from program point of view.

tables are used to pass and get tables from and to the FM.

exceptions are defined actually to help you understand why error occurred in the FM if any.or to do some steps according to the exception raised.

hope this helps
