3819108 - Error: "Access is denied: user is not allowed to access the resource" when delegates attempt to access the Expense & Adjustments page (Travel Allowance)

I am a delegate for an Approver, but when I try to open the "Expense & Adjustments" page for a report, I receive the error: "Access is denied: user is not allowed to access the resource." How can I resolve this issue or what permissions do I need to view this page?
