Description

A few rio_ed__Attendance__c objects were deleted from RIO with a null value for rio_ed__Booking__c .

Resolution

This would occur when a class is being rescheduled to a shorter period or being cut short.

The bookings and attendance that were allocated for slots or blocks which were previously existed/planned will be removed in this case.

For example, when a Session (class running from 1st January - 30th June) has been cut short to 1st January - 31st May instead, anything which was planned for 1st June onwards will be deleted.

It is also worth noting that when the bookings are no longer existing, the deleted attendance records can no longer look up to the deleted bookings too, hence being marked as null.
