In Concur Travel Requests, Per Diem for overnight trips is added as an Expense Type. Later, when you are creating the Expense Report from the approved Request, the Per Diem expense type is not transferred because in the Request, the Per Diem is a lump sum for all days, and on the Expense Report it has to be broken down into each day.

The Travel Expense Report uses the phrase Travel Allowance instead of Per Diem. Don't worry, it's easy to understand. You create Travel Allowances (per diem days) by creating an itinerary. The itinerary is built with "stops," so to create an itinerary you need at least two stops: The first is where you traveled from and the destination, and the second stop is the reverse of that. For example, you fly from Baltimore to Chicago (stop 1) and you also travel from Chicago back to Baltimore (stop 2).

Once you've built the itinerary, you can designate what meals you actually want to claim. The screen has a line for each day in the itinerary with check boxes for meals to include or exclude. The meal allowances are based on the day of travel (first and last are reduced) and the location of the trip. In the previous example, the travel allowance would be calculated based on your start and end dates and the destination: Chicago. When you're done selecting what meals to claim, you Create the Expenses — which is done with a click of that button. Your travel Expense Report will then display a Per Diem line and Amount that looks very much like it did on your Travel Request. Per Diem is calculated based on GSA rates with the 25 percent reduction for the travel days automatically reduced.

There's a tutorial to help walk you through setting up Travel Allowances to create Per Diem on your Expense Report. Don't skip your Per Diem. Just follow the instructions and you'll be a pro in no time.
