Note To insert a single recurrence more than once, such as to define multiple shifts, you must enter different sequence numbers.

If this check box is selected, resources linked to this calendar and availability type are available on the specified working times. If this check box is cleared, the linked resources are not available during the entire day specified, regardless of the value of the Working Hours Type field and the times you specify in the Start Time and End Time field. Shift Name Working Hours Type A type of time interval such as Monday morning, Wednesday afternoon, or service weekend. For a working hours type, you can define defaults for start time and end time.

Capacity Percentage The maximum utilization percentage of a resource for this working hours type.

By default, LN sets the value of the Capacity Percentage field to 100%. Note Do not confuse efficiency factors with capacity percentages. Efficiency factors affect the lead-time calculation for which the corresponding calendar is used. In other words, they influence the speed at which the work is carried out. Capacity percentages give information about the utilization rate of a resource. Efficiency Factor A variable that LN uses to take into account differences in the daily availability of a resource, such as when working overtime, hiring extra staff, or working in different shifts. For example, if an employee works six hours out of a possible eight hours on a project, the efficiency factor is 0.75. Efficiency factors influence the lead-time calculation in Enterprise Planning.

For example, if a certain employee works better in the morning than in the afternoon, you enter an efficiency factor of 1.1 for the calendar line with the working hours type from 09:00 to 12:00. Shorten the lead time of operations by hiring extra resource for certain work. Note Do not confuse efficiency factors with capacity percentages.
