For this, I added the PlanningCalendar and added a PlanningCalendarRow, as well. Besides, I added a CalendarAppointment and configured it as a template. For the CalendarAppointment, I set the datasource to a global variable which is set via the Process Designer, the global variable has as data type a collection of appointment struct fields. You can see all this in the screenshots.
The problem I have is that no appointments are shown in my app, but I also do not get an error… Could you help me what I have to do here?
