Calendars in Manufacturing
To plan production orders or to calculate available capacity in Manufacturing, LN needs to know the hours that are available. In LN, calendars are used to record the availability of resources.
Lead times and production planning
In production planning, LN uses lead times to determine when an operation is finished, and the next operation starts. To obtain reliable planning dates, the availability of resources must be taken into account. For example, a work center can be occasionally unavailable, due to weekends, holidays, or maintenance.
For more information, refer to the online manual topic Lead times in Manufacturing.

To view the available combinations of calendar codes and availability types, start the Calendar Availability Types (tcccp0150m000) session. You can sort the records by calendar code or by availability type.
To view a calendar's working times, efficiency factors, and capacity percentage, use the Calendar Working Hours (tcccp0120m000) session and find the applicable calendar code and availability type.
If a planning date is not within the period defined by the start date and finish date of the selected calendar, that is, no calendar working hours are available for a specific date, LN uses the workweek.
