Users should be also able close fiscal periods/accounting periods by module/subledger area to prevent transactions from being posted back to prior periods. Users should be able to select which fiscal periods are closed by module and this should prevent all users from posting transactions in that module/subledger area if the posting date is in one of the closed fiscal periods/accounting periods. This makes maintaining periods much easier than using the posting from/to dates when you have a number of different users working in different functional areas and you want to close by those functional areas. This makes it simple to close the Vendor subledger and prevent any A/P related transactions from being posted back to prior months while still allowing G/L adjustments and this would then not require maintaining posting from/to dates for each user.
