SAP BI-HR Implementation

Hi,

We have a requirement to implement SAP BI Reporting for SAP HR. Initially they want to go with standard content only. 

In our case SAP HR is separate system(not in ECC). I already found one document in SDN but it is old for BW version  2.0

Please share any BW-HR implementation document for latest version. We have BI 7.0 and HR 6.0.

I really appreciate your help.

Thanks!
