Please help me Activity with id=25 has no allowed slot - please correct that

[sysmonet]

Dear community,

I started a new job, and the school asked me to generate the time tables using fet. This is my first time using it and I have viewed many online trainings and followed the tutorials. However, when I click on generate it shows me the error "Activity with id= has no allowed slot - please correct that".

There is 16 teachers that work in other places and 5 classrooms, the students are fixed in class. One teacher assemble all classes one afternoon.

I have attached my data file, Please help me.

I guess you missunderstood how to add the activities correct.

For example activity 25:
you added a activity with duration 6.
so 6 hours in a row on a single day!

But the TC teacher is only available at 3 days for 2 hours each of that 3 days.

So you should remove activity 25 and enter a new activiy. But you need to split it into 3 parts and change duration up to 2 for each of the 3 splits.
