Payment Hold - Unvalidated Invoices

Hi,

Can somebody explain me the use/functionality aroung the Hold Unvalidated Invoices option at Supplier Level.

I tested enabling the option, creating an invoice and the invoice was put on hold when I save it and the hold was released when I validated the invoice.

I don't understand what is the benefit/use of this functionality because we won't be able to do the payment anyway if we don't validate the invoice......

Any ideas?

Thanks,
