Creation of Multi-Session Events and
Conventions 
This function enables you to create multi-session events with several parallel sessions in Training and Event Management.
You must select the indicator Convention in the Business Event Type Info infotype when you create the relevant business event type.

You cannot use the planning function for a convention. You must create a convention using the corresponding business event type.
· You assign a schedule to each of the sessions. In contrast to single-session events where you can adopt the schedule stored for the business event type, with multi-session events you must define the day schedule of each session individually. This involves specifying time blocks or segments during the day.
· You can allocate resources to the individual sessions as you do with single-session business events.

Once you have created a convention, you cannot change any of the data for it. For example, you cannot change the resource reservation specifications.
· You can book attendees for the main event.

You cannot book attendees for the individual sessions.
There is no integration with Time Management for conventions. For this reason, no attendance records are written to Time Management for attendees.
