After several weeks of writing I am happy to share the result.
The new book Integration SAP BusinessObjects 4.x BI Platform with SAP NetWeaver is planned to be available on the bookshelf by end of October / beginning of November.
The book is focusing on the installation and configuration of SAP BusinessObjects 4.x in combination with SAP NetWeaver BW, SAP ERP, and SAP NetWeaver Portal.
You will learn about things like the data connectivity options, integrating your SAP users and roles, integrating content into the SAP NetWeaver Portal, integrating BEx Web Applications into the BI Launchpad, … and many more.
The book is based on the SAP BusinessObjects 4.0 and 4.1 release.
I hope people find the information useful and enjoy reading the book.
