Oracle General Ledger provides several methods to create and update daily currency conversion rates. For manual updates, the Currency Rates Manager user interface is accessible from both the Functional Setup Manager (for initial setup) and the General Ledger's Period Close work area (for ongoing maintenance). For bulk updates, users can download a spreadsheet template from the Currency Rates Manager, populate it with rate data, and upload it. For automated, system-to-system updates, the recommended approach is to load data into the Daily Rates open interface table and run an import process.

A. The Currency Rates Manager is not accessible only from the Functional Setup Manager; it is also available in the Period Close work area.

B. Existing transactions are immutable regarding their conversion rates. Updating rates is a master data function and does not involve editing posted transactions.
