What is true about a voucher that supports a canceled trip?

A voucher that supports a canceled trip typically requires electronically attached receipts to substantiate any expenses incurred prior to the cancellation. This requirement helps provide the necessary documentation for financial accountability and ensures compliance with travel policies. By requiring receipts, the voucher process maintains transparency and accurately reflects any costs that the traveler may seek reimbursement for, even in the event of a cancellation. This leads to better tracking and allows finance departments to process vouchers in a more informed manner.

The other choices may not align with standard procedures for handling vouchers linked to canceled trips. For instance, not all vouchers necessarily need to be approved by a supervisor, and the assertion that it does not require receipts entirely overlooks the importance of documentation. While some systems could automate aspects of financial processing, it's not universally true that a voucher would be automatically created and sent to finance without the required documentation first being submitted.
