Combining 2 subject into 1 slot

[Info]

Is there anyway to combine 2 subject into 1?
I used "Two activities are grouped" and "A set of activities have the same starting time" but it still show extra hour when generate.

"Two activities are grouped" = not the same slot
"A set of activities have the same starting time" = same starting slot

it's a bit on depending of your correct needs.
You might use "A set of activities have the same starting time", setup the correct students structure or just add a new subject with "both subjects names at the same time"

Thank you but using "A set of activities have the same starting time" still showing the message of extra slot detected

Cannot optimize for subgroup TINGKATAN EMPAT BERLIAN PM Automatic Subgroup, because the number of hours for subgroup is 59 and you have only 57 free slots from constraints students set not available and/or break.

I wonder what I did wrong. Attached FET file.

And where can I find "both subjects names at the same time"? I couldn't find it anywhere.

You can't place 2 activities at the same time if they have got the same teacher or students. that is impossible.
You can fix that by:
a) doing the correct students struture. see https://www.timetabling.de/manual/FET-manual.en.html#id_12
b) removing the dublicated teacher/student from the second activity
c) just place them all into a single activity

You can find "both subjects names at the same time" if you just add A subject by FET -> Data -> subject. (FET will ask for ONE subject, but you can simply write BOTH at the same time. For example: Instead of two subjects "Mathe" and "English" just write 'one' subject "Mathe/English".)

Understood very well, thank you very much.
