In the Calendar & planning module, three different types of calendar items are used:
General calendar items are items which an employee has entered in his own calendar or the calendar of one of the other employees and which are not directly related to a project, project element, customer or contact person. In the month calendar and planner the text entered in the "subject" field will be displayed with these items. The general calendar items are unstructured items as opposed to planning and appointment items.
Planning items are calendar items which are directly related to a project and project element. Planning items are entered in the agenda by either an employee who has been assigned sufficient planning rights (planner) or by the employee themselves.
The relationship between the different objects for a planning item in the Calendar & planning module can be described in the following way:

An appointment item is an appointment between an employee and a customer or contact person of a customer.
