Remarks: I am going through a decision process right now with my client regarding this configuration.  When my client first came up on SAP 9 yrs. ago, they only had 1 currency.  Since then they have made acquisitions and now have multiple company codes with different currencies.  What I have found out is that once you set up a Company code for only one currency you cannot turn on Multiple/Parallel currencies in that company code.  Fixed Assets are affected and so are all the AP & AR transactions.  AR & AP can run into issues when it attempt to create and additional posting to the Group Currency because of Exchange Rate differences.  

In my opinion, I beieve it was a major mistake not to have turned on Additional Local Currencies from the beginning.  What this does is allows you to establish a "Group Currency" in the FI Module.  In table GLT0 you can see that there are columns way out to the right when you view postings via SE16 in columns titled AMOUNT.  These are the group currency postings.  You can then generate reports that pull this detail for consolidated reporting.
