This transaction is used to administer system calendars.
The calendar function consists of two elements: one or several “system calendars” and the corresponding “public holiday calendar”'.
System calendars can be assigned to currencies and countries, for example. The system identifies such calendars by the name of the system calendar. Thus, the calendar for USD (US dollar) is called 'USD' and the calendar for Germany 'DE'. The corresponding public holiday calendar for the year carries the same name plus four digits for the year.
