Category Management 
Use
Categories i.e. groups of vehicles whose similarities are defined by certain rules are formed in category management. These rules are evaluated during the vehicle search.
You can define which vehicles you want to be displayed for which dealers.
You can find further information in the FI-SL documentation (special ledger) under
Rules and
Boolean Logic/Syntax.
Integration
You can define categories per vehicles search are, per organizational role, per combination of these two or completely independently of the vehicle search area and organizational role.
You do not necessarily have to work with vehicle search areas to use category management.
Prerequisites
You have defined rules in the Customizing activity Define Vehicle Categories (transaction OVELO20) and ordered and prioritized these rules in the activity Assign Roles and Vehicle Categories (transaction OVELO21).
Features
When you define these rules, you can fill specific table fields, which reference to the vehicle or the vehicle searcher, with values and then link these fields to mathematical expressions using Boolean operators.

Only tables in the vehicle table can be taken into account for vehicle data, not configuration characteristics.
- A vehicle can belong to more then one category.
- For each vehicle that corresponds to the search criteria, the system checks the rules that have been defines and evaluates them in the given sequence. As soon as the system finds a rule that is "true", the appropriate vehicle counts as having been "found". If no rules are "true", the vehicle is excluded.
- The vehicles that are found appear in the vehicle overview in the order in which the categories are searched. By skillful prioritizing, therefore, you can ensure that the vehicles that you want to be sold quickest appear at the top of the vehicle search hit list.
Example
The categories and their sequence could look similar to those listed below for a dealer that belongs to the organizational role "Dealer Müller":
- Category 1:
Vehicles that are not displayed, belong to dealer Müller and have not been sold to the end customer yet
Displayed = ' ' AND customer = 'dealer Müller' AND end customer = ' '
- Category 2:
Vehicles that are not displayed and belong to dealer Müller
Displayed = ' ' AND customer = 'dealer Müller'
- Category 3:
Vehicles that are displayed and generally available for all dealers
Displayed = 'X' AND availability = '02'
