Hello Liviu,
is it possible to introduce the option to lower the weight under 100% of "Not available Time" for teachers?
So he/she can choose time by preferences and not in obliged fashion. When "Not available time" is under 100% FET can try to break it.
Thanks.
Davide.
You can use constraint activities preferred time slots, selecting only the teacher. Please ignore the warning there.
You can add even multiple such constraints, with different weights, for the same teacher. The highest weight will be considered for each slot.
