STAT Accounts

 Can anyone point me in the direction of a 'how to' or best practices guide around using STAT accounts. We are looking into using them but need to evaluate the unitended consequenses. How do we prevent users from loading actual financials to these account, what are the repurcusions for FSG's and standarg GL reports, do we need to create new JE templates? Any advice would be greatly appreciated.

Thanks in advance.
