You have the following options:

• If you select None, the transactions will not be settled.

• If you select Open transactions, the transactions will be automatically offset against open transactions according to the First In First Out (FIFO) principle.

You can choose manual settlement of the transactions in Automatic settlement. Therefore, when you type orders you can settle the invoice with previously recorded open payments or credit notes, or you can settle a credit note against one or more invoices.
