See per diem advance Policies and Guidelines on how to request an advance. A per diem advance form must be completed to initially receive the advance. After the trip, the reconcilation of the advance is processed in Ariba.
Select Advance Received in the Add Item box.
The advance amount is listed as a negative amount and is deducted against all the travel expenses.
If the per diem advance is more than the actual cost of the trip, you owe the excess to the University. Submit the ER print version with your check to the Travel Office.
