MyExpense is prompting an alert that my expense report is over the $79 meal allowance, but my expense report is within the allowable amount. Why is this happening?

MyExpense looks across all of an individual's expense reports to check for policy compliance. In this situation, the alert is likely displaying because the expense report owner has another expense report with meal expenses on that same day that is causing a daily meal allowance overage. You can search through your expense reports to find other meals on the same day that are causing the alert to display.
