Re: Difference between OBS and EPS in primavera P6

The Organizational Breakdown Structure (OBS) is a hierarchical based structure that represents your organization. The Enterprise Project Structure (EPS) is also a hierarchical based structure that represents how your projects are organized.
The OBS and EPS are combined together through the responsible manager field on the EPS structure, project folder and WBS level. The Responsible Manager field is the OBS and this determines what users can gain access to the Project. When you create a user, you have to give them Responsible Manager assignments in order for them to see projects.
Your EPS and your OBS need to have a one-to-one relationship. If you give a user a Responsible Manager assignment (OBS) that is not tied to an EPS, Project or WBS level, they will not see any projects when they log into the Primavera Client application or the Web Application.
Hope this helps
