Use the ExtendDueDate function if you want to extend the due dates on the invoice. Invoice date will be extended with the same number of days as the original invoice, up to a maximum of 30 days, and can only be used once per invoice.
This function should be used sparsely. One example when this could be used is if the customer has not received the original invoice.
Please note that this function is only available for Direct Invoice.
