Resource being assigned to projects with no project role
Why does a resource not have a role when being assigned to a project?
This is due to the enterprise role of the user being assigned not having a default role set for the project type(s).
The default project role specifies what role to give a new team member who is added to a project as a result of an approved resource request in Team Manager.
You can edit the enterprise role and assign defaults for each project type.
