Working on an expense report.  

I have two big issues:

1. I checked into a hotel on Oct. 30 and charged one meal to my hotel room. Since I checked out on Nov. 3 (and traveled to a different hotel), the total charged to my card was on Nov. 3 and includes the meal.  I itemized the meal and showed the correct date, but doesn't seem to make a difference.

2. I used my corporate card for a meal on Nov. 2. It shows up on my available expenses with a date of Nov. 3.  This puts me over my daily per diem for Nov. 3. No way to change the date of the expense.  

These two issues make my over my per diem for Nov. 3 and I have heard I am liable for all of the overage with no ability to correct the date (I have documentation showing correct date)

What are my options?  How can I fix this issue and avoid paying for travel meals that should be covered by my employer?
