Fet does not generate some timetables

[Lautaro]

Hello.
I am learning to use FET and have this newbie question. After completing the data, and generating the timetable, FET works perfectly. I can view the timetables for teachers. But not the timetables for each room. What am I missing?

Thanks for your help.
Lautaro.

Space constraints are missing.
