Hi Rodrigo,
As a starter I would read SAP Contact Center SP8 release note 2039432. Chapter 3.4 speaks about BusinessObjects. Also SP9 release note has some content for BusinessObjects, see note 2181114.
Next place to study the topic would be Installation Guide chapter 6.8 Installing Reporting for SAP BusinessObjects. Easiest way to access this documentation is via www.help.sap.com/contact-center70/ Then select link "Guide Folder" under Installation and Upgrade Information chapter. That should take you to page where you can find "SAP Contact Center 7.0 Installation Guide".
Regards,
Jukka
