Sometimes you want a copy of an existing company for testing or because you need a new GP company with settings like an exiting one. The Copy Company tool in the Professional Services Tools Library can handle this.
Once you fire off Company Copy you get a choice to copy from one company to another and you can choose whether or not to copy data and report options and you can choose whether to copy from certain modules. Be sure to check the help document. It will tell you what data is copied from which tables.
