Hello Again Liviu,

Sorry for the trouble. Just now i came to know that my colleague used .fet file from data folder in which the activities were locked.

Regards

Dear Liviu,

A very Good morning :-)

Thanks a lot for the prompt reply.
I am generating the time table using file sent by you.
Any advice so that we don't face this issue again.


One more thing, the .fet file you shared after unlocking is version 7.5.5 and i could not find a download link for 7.5.5. It did generate a warning  in 7.5.4 but opened.

Thanks once again. I will share more details once the generation is complete. In the mean time I am sharing the time table with my colleagues.

Dear Sir

We have been using FET for the last 3 years. Till now it was able to generate without any problem even taking care of difficult constraints. But now suddenly it stopped generating. There is a long pause and it shows random activity with unresolved constraint. Currently it paused at

FET managed to schedule correctly the first 798 most difficult activities. You can see the initial order of placing the activities in the generate dialog. The activity which might cause problems might be the next activity in the initial order of evaluation. This activity is listed below:

Please check the constraints related to following possibly problematic activity (or teacher(s), or students set(s)):
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
Id: 763 (    1/5 - JA - Sci - 7B)
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

Please check the constraints related to the last activities in the list below, which might be impossible to schedule:


There is no added constraint. Everything was working perfectly and it has been generate and resolve even more difficult constraints. This is for the first time that it got stuck and not able to generate the time table. As size of .fet file is more than 1 mb, i have zipped it before attaching.
