Travel Manager: Booking Travel Services 
Definition
The travel manager allows the comprehensive processing of travel requests, travel plans and travel expense reports (see
Travel Manager: Cross-Process Entry).The entry part Booking flight/hotel/car rental, which you use to query the availability of and then book these travel services online, is directed (as is the whole entry scenario) at the occasional user, such as the traveler himself and/or the department secretary.
The following section describes how to enter travel plans using the travel manager.
Use
When you call the Booking flight/hotel/car rental link in the travel manager, you are already creating a new travel plan (see also
Creating a Travel Plan: Travel Manager).You can carry out the following functions:
If a
travel request has already been created with the travel manager for this trip, the required data is automatically transferred to the travel plan.
If you have entered towns in the travel request that do not have their own
Integration
The system automatically creates the travel expenses statement belonging to a travel plan created. As soon as you book a travel service online in the reservation system and save the travel plan, a corresponding receipt for the travel service is created in Travel Expenses.

The receipt for a booked travel service is only created once. For cancellations or rebookings you have to update the receipt in the travel expense statement manually (see also
Travel Manager: Data Area "Expense Receipts").
You can also enter your travel expenses via the travel manager when you have returned from your trip.
Travel plans and their corresponding travel expense statements have the same trip number.
