Fusion GL Security

Hello,

We are in the process of migrating from R12 to Fusion, for our Fusion configuration we have several ledgers setup (one for each country we trade in).

Ledger A is the main area with trade in and has 10 business units setup within it, what we'd like to know is if it's possible to restrict access to the select codes that have been setup up for other B/U's.

E.g in Ledger A, Company 1 is manually entering an AP invoice but they are able to view and select the codes for Company 2 and 3. The same happens in the other sub-ledgers such a procurement (Purchase Orders) and Receivables invoices and Companies 2 and 3 can view each others codes etc.
