The travel expense specification contains the relevant travel expense type information for calculating reimbursement amounts.

Travel expense specifications decide how the incurred travel expenses are to be calculated. The reimbursement amounts for travel expenses can be calculated by per diem or flat rate (accommodations, meals and leg of trip) or by individual calculation (individual receipts).

Travel expense specifications are subdivided in specifications for per diems / flat rates and for individual receipts.

Together with the trip destination, the travel expense specifications for per diems / flat rates decide which reimbursement rates are applied by Travel Expenses when the reimbursement amounts are calculated.
