The way that settlements for a credit note and invoice will be handled. The following values are used: None (the transaction will not be settled automatically when the invoice is posted; this is the default value if the Automatic settlement option is cleared in the Accounts payable parameters page), Open transactions (the transaction will be automatically offset against open transactions according to the First In, First Out (FIFO) principle; this is the default value if the Automatic settlement option is selected in the Accounts payable parameters page), and Designated transactions (the transaction will be settled with regard to a specific invoice). This field is available only if the selected invoice is not associated with a purchase order.
