Calendars

A calendar is a combination of a calendar code and availability type, both of which are defined for the resources used in manufacture.

Calendars for warehouses and buy-from Business Partners are the exception.

A calendar can be defined at several levels:

Resource Package Session
Company Common Companies (tcemm1170m000)
Site Common Sites (tcemm0150m000)
Enterprise Unit Common Enterprise Units (tcemm0130m000)
Department Common Departments (tcmcs0565m000)
Warehouse Warehousing

Calendar Code: Warehouses (whwmd2500m000)

Availability Type: Warehouse Master Data Parameters (whwmd0500m000)

Buy-from Business Partner Common Buy-from Business Partners (tccom4520m000)

The calendar code is often related to the resource that performs the operation: work center, warehouse, department, business partner.

If no resource can be found for offsetting, the calendar code is searched for on global level: enterprise unit level, site level or company level.

Which calendar is used for planning purposes depends on which levels the calendar is specified. LN checks all levels to determine which calendar must be used. For example, if a calendar is required for an activity on a resource, LN first searches for the calendar that is defined for the resource.

If no calendar code is found, the department level, the enterprise unit level or site level (if multisite is implemented), and finally the company level are successively checked.

If all resources use the same calendar, you must only specify the calendar code on the company level.

Not all offsetting is linked directly to a resource. Example: Determining the order horizon data for a specific plan item. In Enterprise Planning the specified item is used to determine which calendar is used: the calendar linked to the enterprise unit or the calendar linked to the default warehouse of the plan item.

It is possible to overrule a specific calendar. Example: You replace calendar COMP/2SHIFTS (= calendar code/availability type) on the selected department with calendar COMP/3SHIFTS to simulate the effect of using a different availability type.

To view the simulation result, you must add an overrule for the active scenario in the Scenario - Overrule Calendar (cprpd4160m000) session, COMP/2SHIFTS →COMP/3SHIFTS and run Generate Order Planning.
