Activities in fix period or time

[habids]

hi,
may I know how to fix time/period for certain activities. I am asking because I can't generate the timetable and have a warning notice.

Link fet warning

Data--> Time Constraints --> Activities --> Prefered Times --> An Activity has a set of prefered time slots

Yes, you done it correct, but you added for activity with id 284 more constraints that are conflicting.
Maybe you add room constraints and the room is not available at that time.
Maybe you already fixed an other activity at that time with the same teacher or students.
Maybe you added a not available time constraint for the teacher on that day.
...

Go to FET -> data -> activities
select activity 284
Check the right window. You should see there many constraints that are refering to this activity. There is probably an other constraint visible, that is conflicting.

Thank you Volker. What happens is actually a human error setting. I check one by one and confirm my setting has an error. that is why I received the notification.
