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 (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 Enterprise field shows whether a resource is from the enterprise resource pool (enterprise resources: Resources that are part of an organization's entire list of resources. Enterprise resources can be shared across projects.) (Yes) or the local resource pool (No).
How Calculated Information about the enterprise resource pool is set on Project Server. When you open an 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.) and connect to Project Server, the information about enterprise resources is reflected in your project plan.
Best Uses Add the Enterprise field to a resource sheet when you need to see which resources are enterprise resources and which are added from your local resource pool. This is useful when you have a mix of enterprise and local resources in your project plan, or when you're getting ready to import local resources to the enterprise resource pool.
Example You have 15 enterprise resources and 10 local resources assigned to tasks in your enterprise project. To see which is which, you insert the Enterprise column into the Resource Sheet, and group the resources by whether they're an enterprise resource.
