Final answer:
A transaction may be canceled if there's an insufficient account balance in the banking database, often leading to a transaction rejection or an overdraft fee.
Step-by-step explanation:
An example of a condition that may cause a transaction to be canceled is if there is an insufficient account balance in a banking database. When you attempt to make a purchase but do not have enough money in your account, the transaction is typically rejected, and you will need to use an alternative payment method.
In some cases, banks might allow the transaction and charge an overdraft fee, resulting in a negative balance that can be costly to carry.
