This is where you enter the basic structure of your timetable, ie. days and periods, you also enter the various miscellaneous items, ie. breaks assemblies, and you are able to tweak the solving engine if you require.
Please Note:
The day and period details, as well as the miscellaneous items are relevant to the timetable that you're working on. The solving engine affects the program and all timetables that need to be solved will use these adjusted parameters.
