An event can be related to other events. These relations can be clarified by groupings.

1. Assign an Occasion type to any event for easier statistical anlysis.
   Note: The occasion type can be marked as a mandatory field by a user with administrative rights.
2. Assign an Event group to different events that are to be grouped together as a unit (quote, order, invoice).
   a) Click on the Group button to automatically set the event number as the group number.
   b) Enter this group number manually for the other events that are to be booked together.
