Help with Activity 01 has no slot

[AntoinetteGen]

Good morning, I have tried all the suggestions you made to one of the other timetablers.  Could you please help me? . My timetable is for 6 different grades/ years for 8 lessons. I have blocked off the snack and lunch breaks and the registration.  Should I maybe remove those and only do the lessons?You cannot view this attachment.
I have now managed to get it to run, but it won't split the 5 lessons into 5 lessons - it insists on doing them in blocks of 5 lessons

Good morning,

You need to add the activities as split, instead of say activity id 1 with duration 6 add it as (2+1+1+1+1), an activity split into 5 components.

A skilled C++ programmer can convert from your file to the correct one, or maybe some tricks with import/export CSV files.

Yes, i recommend to delete the breaks, since they are every day the same, so unneeded information. In my opinion you should use a break constraints only if it is different on at least 2 days.

If you want to keep the breaks, then you need to split the activities. You can not place ONE activity over a break, it must be split into 2 (or more) parts.

Thank you!  I thought I had read you needed to put in the splits, but it won't let me split the duration?

Sorry, but to whom are you replying? I do not understand.

It's impossible to modify the split. You sadly need to delete the activity and add it once again with the correct split.
