Extended Search 
The extended search provides the option of executing queries for car rentals in more detail by adding additional selection criteria. It lets you restrict the selection to vehicles that suit your specific requirements before running the availability query.
You have activated the extended search for displaying car rental offers. You do this in Customizing for SAP Travel Planning under Dialog and Planning Control ® Travel Planning Control® Define Price and Availability Strategies.
The extended search is available if you have created a travel plan and started a car rental request.
If you use the Amadeus global reservation system, you can carry out the search based on one of the following selection criteria or a combination of criteria: If your company is connected to the Sabre reservation system, you must specify the car rental provider.
The Branch Office option allows you to choose a specific car rental office as the pickup and/or dropoff location. The default value in the standard system is the branch office at the relevant airport terminal.

If you specifically enter a certain car rental provider in the extended search, this overwrites any possible provider list with most economical vehicle that may have been activated in Customizing. In this case the query does not return a list of the most economical vehicles provided by all car rental providers, but rather a list of all available vehicles for the specified provider according to your search criteria.
