The Peak field indicates the maximum percentage or number of units for which a resource is working at any one time on an assignment.
Data Type Percentage/Number (percentage/number field: A type of field whose content is a value that can be expressed as either a percentage or a decimal number. For example, in the Assignment Units field, one full-time assigned resource can be expressed as 100% or as 1.00.)
Entry Type Null field (Null field: A field that displays no actual information but that sets up the field for information elsewhere in the view, particularly in the Task Usage or Resource Usage view.)
Best Uses Add the Peak task field to the table portion of the Task Usage view when you want to see the corresponding Peak fields for the individual assignments on the task.
Example You are reviewing the peak resource allocations for task assignments. You add the Peak field to the Task Usage view. No information appears in the Peak field next to the task name itself. However, the peak values for the tasks' assignments appear in the Peak assignment fields below each task name. You see that for the "Coordinate trade show" task, Jamie has a peak allocation of 125 percent and Chris has a peak allocation of 50 percent.
Remarks Although you can add the Peak field to a task sheet such as the Gantt Chart, no data appears in the field. It’s a null field, provided to give context to the Peak assignment field in the Task Usage view.
