If expenses on a trip authorization must be updated, which action is required?

The correct action required when expenses on a trip authorization must be updated is to indicate incurred expenses and provide proof. This approach ensures that all financial transactions are accurately recorded and accounted for in accordance with the policies governing travel expenses. By providing proof, such as receipts or invoices, you support the validity of the expenses claimed, which helps maintain transparency and adherence to regulations.

Submitting a new authorization typically is not necessary unless there are significant changes to the trip that warrant an entirely new approval process. Requesting approval for all expenses may be redundant if the expenses have already been incurred and documented properly. Leaving the authorization unchanged until the trip concludes can lead to inaccuracies and potential issues with reimbursement or compliance with travel regulations, making it an ineffective choice in this context.
