If suppliers' invoices are booked as open items in an account payable, open items are balanced at the time of the payment.
Selection of the items: Please click on the amount. Balance is filled up to the total amount. If there are more items, the following with the same reference number are automatically assigned. If no items can be found, the system searches for following items of the same supplier. By clicking the right mouse button, the assignment can be set to zero. A manual entry is also possible.
