Like the teams, the list of all locations availble for assignment are presented on the left and the ones to be used are on the right. This is usually desireable but not required. Of Course not requiring locations makes more dates and times available for scheduling. Locations like officials can always be assigned later but this may prve a tedious task. Lastly indicate whether officlas should be assigned, how many per game , how often then can officiate and from what list of offcials.
Officials have little affect on the schedule as they are assigned after the fact.
If an official is available and doesn't play on any of the teams then he vcan be used. Note that Officials can be assigned later from the Game List window automatically or manually per game. Well that is about it. Once you click on OK , MM will attempt to create a schedule. Before clicking on the OK, you are still allowed to go back and change any parameters you want.
