Where do I find it?
Configuration > Business Data > Seat Categories
What does it mean?
Seat categories define the different types of seats or classes you offer. If you do not offer more then one category, you still must register at least a placeholder (i.e. normal or standard) in order to work with the system. You need to register here all seat types across your business. For example 1st class, 2nd class, Standard etc. You must specify the appropriate prices for each chosen seat category later on in the corresponding in the Priceplan.
What should I do?
Enter all the seat categories you use and choose a useful Code (you'll need the in Priceplans again in order to identify the seat category).
