An invoice is flagged by AMS360 as "future" based on the setting of a field in Agency Setup, the "Number of Days to Invoice in Advance of the Invoice Effective Date".

When an invoice is posted, the Invoice Effective Date is compared to the Current System Date. If the difference between the two dates, expressed as a "number of days", exceeds the "days to invoice in advance", ( e.g. 45 days), the invoice is not assigned an invoice number and it does not post to the general ledger.

The system checks future invoices each time Daily Process is run to determine if the "days to invoice in advance" threshold has been reached. If so, the invoice is assigned an invoice number and posted to the general ledger.

Although a future invoice is not posted to the general ledger, it is listed in the Customer Register with a zero (0) as the invoice number.
