New Rules for
Periodic Appointments 
Use
As of Release 4.6C, a new interface is available for creating periodic appointments. This provides a more intuitive user guide and an enhanced function range. For example, several rules can now be linked together. This enables associated appointments with different period intervals (for example, every week on Mondays and Thursdays and every first Friday in the month) to be displayed.
For more information, see the documentation on the appointment calendar.
