New company with different tax id

Hi - I'm looking for full documentation on how to add a 3rd company to our JDE environment.  This company will have it's own tax identifier, and we will need General Ledger, Accounts Payable, Accounts Receivable, Fixed Assets, Payroll, Human Resources, Capital Asset Management, Job Cost, Contract Billing, Inventory, and Purchase Orders/Subcontracts set up.  Is there a document that would help us with all of this?

Thanks, Kati
