The Head Referee can enter conflicts the official may have with teams, division(s), league(s) or club(s). The automatic assigning procedure will not assign any games involving those organizations to the official.
In manual assigning, the Officials Assignor will be warned if an official has an exception with a certain teams, division(s), league(s) or club(s). The Officials Assignor can manually override this conflict warning and make the assignment anyway. Only Head Referee and the Officials Assignor can view these exceptions.
