Entering Journals for a Future Period
You can enter journal entries for as many future periods as you want. For example, you might want to enter journal entries for the following month while you are closing the books for the current month. You control the number of future accounting periods for which you want to allow journal entry when you define your set of books. General Ledger automatically assigns a status of "Future-Entry" to the appropriate number of accounting periods following the latest open accounting period in your calendar.
Although you can enter journal transactions to any accounting period with the status of Future-Entry, you cannot post journals into a period until you open the period.
