What does Responsible Manager mean within Primavera P6 EPPM?

A.
the person responsible for resolving the Issue

B.
the person who identified the Issue

C.
the element from the Organizational Breakdown Structure associated with the Issue

D.
the manager to which the Issue has been assigned

Explanation:
Note: When you associate a responsible manager with an EPS Node, any projects you add to that
branch of the EPS are assigned that manager element by default.
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.
