Data Type Yes/No (Yes/No field: A type of field with content set to either Yes or No; also known as a Boolean field or a True/False field. For example, the Recurring field indicates whether the task is a recurring task.)
Entry Type Calculated or entered (calculated or entered field: A field in which the value is determined by Project based on information in other fields. Information that you enter in the field yourself overrides calculated values.)
Description The Team Assignment Pool field shows whether the current resource is a team resource (team: A group of enterprise resources who may be assigned as a single resource to a task.) (Yes). A team resource is a single named resource, for example, "Legal" or "Sales," which represents a group of several enterprise resources (enterprise resources: Resources that are part of an organization's entire list of resources. Enterprise resources can be shared across projects.), any of whom can fulfill the work on assigned tasks.
How Calculated If you create a team resource in the Resource Center in Project Server, and add that team resource to your enterprise project (enterprise project: A project that is stored in Project Server to ensure information integrity. To make changes to an enterprise project, users with access permissions are required to check it in and out from Project Server.), this field is set to Yes automatically. You can also change this field from within Project.
Best Uses Add the Team Assignment Pool field to a resource sheet when you need to see which resources are team resources and which are not. Also use this field when you need to create a team resource or change an existing work resource (work resource: People and equipment resources that perform work to accomplish a task. Work resources consume time [hours or days] to accomplish tasks.) to a team resource. You can then assign this team resource to tasks that you want to be available to all members of that team. In Project Web App, team members are able to see these tasks and assign themselves to them.
Example In the Resource Sheet, you create a new work resource named "Marketing." You add the Team Assignment Pool field to the sheet, and change its setting to Yes, making it a team resource. Switching to the Gantt Chart, you assign the new Marketing team resource to several tasks, including "Develop new product brochure" and "Create trade show plan." You publish (publish assignments: If you use Project Server as your team collaboration solution, you publish assignments to notify your resources of new and changed assignments to tasks.) the changes to Project Server. In Project Web App, the members of the Marketing team —Erin, Pilar, and Wilson —see the new tasks assigned to Marketing. Erin and Pilar assign themselves to the "Develop new product brochure" task, and Pilar and Wilson assign themselves to the "Create trade show plan" task.
Remarks Although the Team Assignment Pool field is available for local projects, it is only useful when working with an enterprise project through Project Server.
