Calendar usage

The following tables list the lead time components, the calendar, and availability type that are used to plan the production order lead times.

In addition, the calendar selection logic is described in the subsequent subsections.

Note

A calendar is mandatory for a production department, no further fallback is necessary.

Lead time components for fixed planningSequence to find calendar:
Order lead time (JSC)
  1. Enterprise unit
  2. Company
Lead time offset
  1. Department
  2. Production Department
Planned production time
  1. Department
  2. Production Department

 

The lead time components in these tables refer to planned production orders in Enterprise Planning as well as to JSC production orders.

Routing planning

When you plan with routing operations, each operation is linked to a work center. All lead times, except wait time, use the work center to find the calendar.

Wait time is not linked to any calendar and, therefore, directly subtracted from the finish date.

If no calendar is defined on a detailed level, retrieval of a calendar can require several steps.

Fixed order time

If you use a fixed order lead time, no routing, and therefore no work centers, are involved. The calendar of the enterprise unit is used instead.

Calendar retrieval by item

A calendar is retrieved from these sessions:

  1. Enterprise unit of the plan item in the Items - Planning (cprpd1100m000) session. The enterprise unit is taken from the default warehouse of the plan item.
  2. Companies (tcemm1170m000)

The fixed order lead-time horizon date is planned forward from the current date (date of order planning run) and uses the same calendar.

Generic routing

Both lead time offset and production time use the work center calendar. The logic of calendar selection is the same as for routing planning.

Production Schedules

Production Schedules only have one lead time element: the Order Plan Lead Time, defined in the production model of the repetitive item.
