Closed

If this field is selected, the sequence is closed (not available for use). Otherwise, the sequence is open (available for use). Only one record for a category and date range combination should have a status of Open. All other records should have a status of Closed.

If you have a sequence of invoices defined, but you do not use all of them by the end of the defined date range, you must close the sequence and leave the rest of its numbers unused.
