| # Overview of calendars and periods This topic presents an overview of the Calendars and Periods module. In the Calendars and Periods module, you can define calendars and time patterns to use throughout the ERP Enterprise packages. Concepts In the Calendars and Periods module, you can define the following types of data, for use in other parts of ERP Enterprise: Recurrences Patterns Calendars Periods The following table describes each of these concepts.
Concept | Description
Recurrence | A recurrence is a repetitive pattern of dates, such as “Biweekly on Mondays and Fridays”, “The 27th of each month”, or “January 1st of each year”. Recurrences are used to build patterns and calendars. In the People package, you can use recurrences in assignments.
Pattern | A pattern is a scheme defining the day of the month, the day of the week, and the time of the day you want an activity to be carried out. Patterns are defined by using a combination of recurrences, exceptions, and times of day. The Order Management and Enterprise Planning packages use patterns to define delivery moments, shipping moments, and fixed delivery patterns.
Calendar | Calendars define the working times or opening times over a large range of dates. Calendars can also store efficiency-related and capacity-related data. You use calendars to define the working times of employees, work centers, and warehouses and information on the working dates and times of business partners, required to plan deliveries.
Period | Periods divide a year into regular intervals, such as weeks, months, or quarters. You use periods for statistical, financial, hours accounting, planning, and cost controlling purposes, especially in the Sales, Procurement and Project packages.
Dependencies To help you understand the structure of this module, some of the dependencies between the concepts are described below: A pattern is based on one or more recurrences. Calendars are based on availability types and calendar recurrences. A calendar recurrence is based on one or more recurrences. For dates with no available information, the calendar falls back on the standard calendar. In the following simplified diagram, the outward pointing arrows represent information that is made available outside Calendars and Periods.
