Bookings behave differently based on the Type of the Template they are using.
a) If a Booking has a template with Type=Booking, or the Booking has no template applied, it is a “normal Booking”
These bookings show in the Workspace Schedule and can be linked to Projects or Tasks to also show in that Project Schedule.
Bookings can have both Members and Resources involved, and you can submit Time Reports for Bookings.
b) If a Booking has a template with Type=Personnel, these Bookings cannot be linked to any specific project or task.
These bookings show in the Workspace Schedule and in ALL Project Schedules.
You cannot Time Report on Personnel Bookings and only Members can be Involved, not Resources.
