Ending Invoice
On the Invoice, Debit and Credit Memo Sequences form, enter an ending invoice, credit memo, or debit memo number for this sequence. Alphanumeric key logic is applied to all entered values. For example, if you enter AB3 and your invoice length is set to 12, the ending value becomes AB0000000003). This field is enabled only when you create a new record.
On the Void Unused Invoices form, the ending invoice for the selected range is displayed.
