Setting a maximum percentage of the M&IE per diem


The way that e-xpense uses your setting in the Percent of Maximum Per Diem for First and Last Day field depends on whether the employee is entering a pre-authorization request or an expense report, as explained in the following table.

In this type of expense form...

The following happens...

Pre-authorization request

If the number of days that the employee is traveling is greater than two, then e-xpense calculates the total estimated cost as:

(2 * percent of maximum per diem / 100 +
(number of days - 2)) * cost per day

If the number of days that the employee is traveling is equal to or less than two, then e-xpense calculates the total estimated cost as:

(number of days * percent of maximum per diem / 100) * cost per day

For example, let's say that you set the Percent of Maximum Per Diem for First and Last Day field to 75. When the employee travels for five days, and the daily M&IE per diem is 46, then the total estimated cost would be (2 * 75 / 100 + (5 - 2)) * 46 = 207.

Expense report

When the employee clicks Per Diem, e-xpense calculates the cost for the first and last day as:

per diem cost * percent of maximum per diem / 100

If the employee is entering multiple reports for a single travel request, then the way that e-xpense behaves depends on your setting for the Prorate per diem for multiple expense reports field on the Parameter Setup screen, Expenses tab.

Note: Your setting for the Percent of Maximum Per Diem for First and Last Day field does not affect how e-xpense determines whether the employee has charged over the per diem rate.
