Generation always stops on same activity

[D.alexander]

Hi,

I have used the same activity structure to generate a timetable for 3 years now. But this time the generation keeps stopping at the same activity (number91, id644). I have reviewed the data and deleted whole year groups and reenterred. I have tried deleting all space constraints. But always gets stuck on id644.

I am sure i have overlooked something obvious. But i would appreciate a second set of eyes.

Many thanks in advance

Hello,

If you generate and stop viewing the highest stage timetable, enter view students timetable. This will show you that the activity id 645, which has students 13-ELI, has no place, because it has duration 2, and all the other activities in the timetable of these students have also duration 2 and there is no place for them. I attach a screenshot.

Activities with duration 2 cannot split over a break/not available slot.
