One of the areas we worked hard in the 2nd quarter of 2013 was to collect and document methods of how to integrate the Microsoft BI stack with SAP backend systems like SAP ERP and SAP BW. The result of this work meanwhile is documented and released as a whitepaper
The paper gives an overview of different methods and different integration pieces to connect the Microsoft BI stack to SAP Netweaver based applications. We certainly will work on even better integration in the future which we will document accordingly. We will keep you posted.
