If an item is returned after a lost bill has been paid and the library’s policy is to void the replacement fee for lost-then-returned items, there will be a negative balance in the bill. A refund needs to be made to close the bill and the circulation record. Once the outstanding amount has been refunded, the bill and circulation record will be closed and the item will disappear from the Items Out screen.
If you need to balance a bill with a negative amount, you need to add two dummy bills to the existing bills. The first one can be of any amount (e.g. $0.01), while the second should be of the absolute value of the negative amount. Then you need to void the first dummy bill. The reason for using a dummy bill is that Evergreen will check and close the circulation record only when payment is applied or bills are voided.
