Changes to the Timetabling script

In v 8.0.63 an above there have been changes when you add bookings to the calendar.
​When adding all bookings for this one teacher to calendar, the script pauses at each record in the portal. This allows users to see where they're up to. It also allows users to skip records if they don't want to schedule them at this point in time.

2. No need to 'Check for clashes' any more. The script should tell you along the way if it's having trouble finding spaces for a particular student. And the records will be shaded yellow on the calendar automatically, without having to click the 'Check for Clashes' button. 

3. The system now checks for more than just teacher and venue clashes. It also checks for clashes with a student's own timetable. The time field will be shaded differently for each clash:

• yellow for teacher clash,
• red for student timetable clash,
• blue for venue clash,
• and orange if it's a group lesson.

(It can only show one colour at a time obviously so if there is more than one clash affecting a particular lesson, you won't know until you change the time and see if it's still coloured.)
