Data Type Enumerated (enumerated field: A type of field whose content is selected from a list of predefined choices. For example, in the Accrue At field you can select the way resource costs are accrued from a list that includes Start, Prorated, and End.)
Entry Type Calculated (calculated field: A field in which the value is determined by Project based on information in other fields. Project may recalculate the value automatically or when you specify, depending on your choice of calculation settings.)
Description The Resource Type field indicates whether resources assigned to this task are work or material resources. Work resources (work resource: People and equipment resources that perform work to accomplish a task. Work resources consume time [hours or days] to accomplish tasks.) are people and equipment. Material resources (material resource: The supplies or other consumable items that are used to complete tasks in a project.) are consumable supplies, such as steel, concrete, or soil.
How Calculated The Resource Type field is derived from the setting in the Type resource field, either Work or Material.
Best Uses Add the Resource Type field to the Task Usage view when you want to view the types of resources assigned to tasks. Also use the Resource Type field when sorting, filtering, or grouping tasks by their resource types. This field can be particularly useful when you want to review all material resources together in the context of tasks.
Example You want to take a closer look at the tasks that material resources are assigned to. In the Gantt Chart, you group the tasks by resource type. All the material resources are grouped together, followed by the work resources.
Remarks In the Resource Usage view, this field is simply called Type.
