Hi

We are in process of Integrating SAP ECC 5.0 Server with BO XIR3 Server .

ECC 5.0 is in one server and BO XIR3 is in one server

I would like to know what are the steps we need to do in different systems

I have gone through BO Integration Kit document by Igno . I couldn't find SAP Bo integration download link in market place .

if any one can tell me step by step process for integration of SAP ECC 5.0 and BO server .

Thanks
