Use
The approval program includes a number of functions with which you can check and approve employee trips in the expense department. The approval of an employee trip takes place via the assignment of a trip status for Travel Expenses. You can set the trip status using the individual entry scenarios or this function or using the approval program for trips.

A trip must have been approved before an advance can be paid and before it can be settled.
