Elective courses

I managed to solve this. Now, another problem that is odd, because time slots look available, but the activity won't fit. It is activity 278, 279 which should be on Thursday at 10,

I'm sorry, but I don't understand. 278 has same teacher and students as 279, so they cannot overlap. Also, 278 has a locked time as:

Time constraint
Activity with id=278 (2 - др Марија Цвијетић - Дидактички материјал и асистивне технологије у инклузивном одељењу (и) - (П),иг8 - Учитељи - 4. година Дидактички материјали и асистивне технологије у инклузивном одељењу)
has a preferred starting time:
Day=Четвртак
Hour=08.00
Weight (percentage)=100%
This activity is not permanently locked, which means you can unlock it from the 'Timetable' menu

No, they should not overlap, but follow one another. Although, as you can see if you deactivate constraints for these activities, the whole Thursday morning is free, but the sucbect cannot be placed in the time slot after the "П" which is Predavanja (Lectures) (as oposed to "В" Vežbe (Seminar). Although none of the constraints is interferring, the timetable can't generate. I guest that the problem might be in the Classrooms, although I left a lot of classrooms to be chosen from.

Sorry, I don't understand, because your file above was solvable on my computer.

[borivoje83]

It is because I turned off the time constraint for the 279. Try turning it on. (I'm working on the file all the time.)

I turned on preferred starting time for 279. It stopped at ID 1161 I think; I made home rooms for 1161's teacher 100% -> 99%, it solved with difficulty, but it solved, and we got this constraint home rooms broken. I understand with very much difficulty the Cyrillic characters, sorry, but I think these home rooms are all occupied.

Thanks. I will try to loose for a little bit the homeroom constraints.
