How does inheritance work for project groups?

Site or project administrators can create project groups and add member projects to the group, to manage several projects as a single unit. Moreover, hierarchical relationships may exist between projects so that one project can inherit members, roles and permissions from its parent project.

Quite like a project can inherit roles and permissions from its parent project; projects can inherit only permissions via the project group.

Project Groups permissions when granted to users via site-wide roles, also allows the users to access project groups in all cases. Prevent inheritance option for roles does not apply in those cases.

The project in which a user gets permissions through role assignment in project groups appears on the My Workspace > Projects > All Projects page.

The direct roles created in project groups are not made available as inherited roles in the member projects for assignment. The direct project group roles can only be assigned directly in the project group context. These roles are non-requestable.
