Can the same Bank Account be set up in different OUs ?

 Is there a document around setting up AP Bank Accounts that addresses Operating Units sharing internal bank accounts?  For example, we have one SOB for the US and have several US OUs.   But we have a the need to use our bank account for the NW OU to pay invoices in SW OU using the same bank account number, same gl acct number but different entity number (of course).  Is it as straight forward as setting up the same bank account and bank account number in the SW OU which mirrors the setup of the NW OU?  What would be the reconciliation implications?
