Enterprise Roles (5.3) vs Business Roles (10)

Hi everyone,

A quick question about the difference between these two things.  Here is what I'm trying to answer.

In 5.3, when you assign an enterprise role to a user, the approvers are from the roles that comprise the enterprise role.

In 10, when you assign a business role to a user, the approvers are those that are associated with the business role.  It seems there's no way to have the approvers of the roles that comprise the business role be used for approvals.

Is this right, or am I missing a config step somewhere?

Thanks,

Santosh
