Data Type Text (text field: A type of field whose content is text. Examples include the Task Name and Email Address fields. This field can contain up to 255 characters.)
Entry Type Entered (entered field: A field in which you may type or edit information. This is in contrast with a calculated field, in which Project calculates and enters information.)
Description The Group field contains the name of the group that a resource belongs to.
Best Uses Add the Group field to a resource view when you want to be able to display, sort, filter, or edit resources by the resource group.
Example In your project, you have three groups of resources: Plumbers, Construction, and Management. You have added the Group field to the Resource Sheet view and assigned all resources to their appropriate group. If you want to review resource information for all plumbers, you can apply a filter that shows only those resources that belong to the Plumbers group. Resources in the other groups are not shown.
