Create a refresh group if you have a group of MV's that you either want/need to refresh together. A good reason is refresh timing (daily, weekly, monthly, etc.).
I hate to say it, but the MV docs are perty good at tahiti.oracle.com
Have a nice day.

One major advantage of refresh groups is that they allow an option for complete refreshes to begin with a delete, rather than a truncate. In the event of an error during the refresh process, you can issue a rollback to recover the previously stored data set -- with a truncate, of course, you can't do this.

Look in the "Supplied PL/SQL Packages and Types Reference" at the "DBMS_REFRESH" package.
