The primary consideration when planning currency translation is whether you have multiple currencies per entity. Entities are linked to a primary currency in your Microsoft Office PerformancePoint Server 2007application, so business models with multiple currencies per entity require special configuration of the Exchange Rate Model. By default, the Exchange Rate Model uses one currency table, but an additional currency table exists in the model to accommodate multiple currencies for a given entity.
Another planning consideration for currency translation is whether you will have multiple entities that use the same currency, but will use different exchange rates. To accomplish this, you can submit exchange rates by entity, instead of by currency.
