Calendars and Periods

Calendars

Calendars record information on the availability of resources, and make this information available to other LN applications.

You can link calendars to these entities:

• Companies
• Employees
• Departments
• Addresses.
• The various business partner roles

LN uses the most specific calendar. For example, if you link a calendar to a ship-to business partner, this calendar is used instead of the calendar that you linked to the ship-to business partner’s address.

The company's calendar defined in the Companies (tcemm1170m000) session is the default calendar for all the entities that use calendars.

To share the calendar tables between the companies of a multicompany structure, the first day of the week must be the same for all the companies. For example, you cannot share the calendars if one company defines the first day of the week as Sunday and another company as Monday.

Recurrences

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.

Patterns

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.

Periods

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 Order Management and Project packages.

Features of the CCP module

The Calendars and Periods module provides you with the following range of functions to maintain calendars:

• You can maintain unique calendar codes with descriptions, for which you can define availability types and calendar working hours.
• You can derive a calendar from an existing calendar. Therefore, instead of defining calendar working hours for all dates in a range, you only need to specify the exceptions. For example, company-wide normal working hours can be specified in a company calendar, while employee-specific information (such as vacations and meetings) can be stored in the employee calendar.
• You can create the calendars LN applications use for planning and scheduling.
• You can define the standard calendar for a company. Note that, if companies are maintained on the same system, one company can use another company's standard calendar.
• A range of maintenance functions with which you can copy and delete calendars.
