Calling Bi PUB reports from EBS as oppose to stand alone.

Hello,

With EBS 12R how does BI PUB get integrated with the EBS? Don't need great detail. I am looking for an overview.

I am familiar with how to call them in a stand alone mode but not when integrating with EBS.

How does security work? Are EBS responsibilities avallable to BI Pub users?

How are the BI PUB reports launched? What does the user log in to to run the BI PUB EBS report?

Are BI Pub roles related to EBS responsibilities?

THanks folks. Would greatlly appreciate your response.
