Approved Expense Reports if opened via email approval, the page it takes us to is not meaningful.

Hello Team,

Could someone shed lights on the below discussion on the expense approval

1. Create an Expense report and submit to approval

2. Email triggers to all the pool of approvers that an expense report is pending for approval

3. One of the approver opens the links from email and approve the expense report

4.  If another approver from pool of approvers opens the approval link from email (approved expense report), It shows a message "An error occurred while attempting to display the selected transaction.  Please contact administrator. "

We feel that this message should be more meaningful.  Please review and suggest.
