Project profiles
Define a user's access to project-specific information. The Project Management module does not require
that each user be assigned a project profile; however, users cannot access projects unless they are
assigned a project profile or the global profile, Admin Superuser.
Note:
To ensure security at various levels of data, the Project Management module provides two sets of security
profiles:
* Global profiles
Define a user's access to application-wide information and settings, such as the enterprise project
structure (EPS), resources, roles, and cost accounts. Each user must be assigned a global profile. (B)

Note 1: The following diagram illustrates the relationships between a user, the OBS, EPS, and WBS.

Note 2: Users in Primavera P6 require two different profiles to control what they can do in the system; a
Global Security Profile and a Project Security Profile.
