How are Past Due Invoices determined on the Outstanding Invoice Report?

The system is looking at the due date to determine when an invoice is past due. 

• Contracts & Grants (CINV) invoices due date is the date they are created, so they will always show on the Outstanding Invoice Report, when include Past Due Invoices is selected. 
• Customer (INV) invoices due date is set to 30 days later from the current date and can be changed. Once the due date is earlier than today, the INV will appear on the report when Past Due Invoices is selected.
