When enabling Belgian localization, a default functionality regarding posting validation is available. This functionality allows finance administrators to enter a date range in which a number sequence can be used. If a transaction is posted outside the date range, the transaction will not be posted due to a check on the number sequence with the allow date.

If we could have this functionality for other countries we could allow finance to have a smoother period close due to the fact that we can enforce the number sequence used in a transaction.
