If you discover that a traveler included a disallowed expense on their authorization?

If I discover that a traveler included a disallowed expense on their authorization, I would first review the relevant policies to ensure clarity on the specific disallowed item. Then, I would communicate with the traveler, explaining the issue and the reasons for the disallowance. It’s important to provide guidance on how to correct the authorization, ensuring compliance with the policy moving forward. Finally, I would document the incident to help prevent similar occurrences in the future.
