This list (Teachers | Master data | Print) shows the daily balance (target periods, actual periods, cancellations, substitutions) of a teacher for the time range of one month. You can select it in the print selection dialogue window under "Teachers | Master data", "Type of list". The difference compared to the monthly statement is that you get a list with substitutions and cancellations on a daily basis which, however, only considers additional work caused by substitutions, but not the target/week according to contracts. This list shows the ratio between scheduled and actually held lessons.
