Only Credit Invoices with Cover
If you select this option both debit and credit invoices from the supplier will be shown, but the system will automatically uncheck the "Pay" box for all invoices from the supplier in question if the total debt is negative.
Blocked
Check this box in order to show blocked invoices. These invoices will only be shown on screen, but cannot be paid. The block must be cancelled before you can pay these invoices.
Total per Currency
If you check this alternative, you will see a total amount per currency at the end of the list.
Only Authorized for Payment
If you have checked the setting Authorize for Payment?, under the section Accounts Payable under the Purchase tab in the Settings procedure, you will see this option. If you select this option, only invoices with status Authorized for Payment will be included in the list. Invoices are authorized in the Authorize for Payment procedure. Invoices with status Final coded will not be included. If you apply Authorize for payment, the invoice must be authorized before any payments can be made.
