Over allocation occurs when the payment or credit exceeds the total amount owing on the corresponding order. This can occur when a customer performs the following, after making a full payment:
- Removes items from an order
- Replaces an item with a lower-priced item
When an order is overpaid, the following occurs:
- The outstanding amount is applied to all of the order items.
- The overpayment amount is applied as an unallocated amount.
Suppose that after making a full payment to an existing $510.00 order, a customer decides to change a Senior Admission to a Junior Admission. This results in an overpaid balance of $100.00.
The order and its corresponding transaction history are modified as follows:
