EP integration with SRM,BI and ESS/MSS

Hi,

I am a SAP Security consultant and currently working on an implementation project. Request your help for the below activities :

1) EP 7.1 to be integrated with SRM 7.3

2) EP 7.1 to be integrated with BI 7

3) EP 7.1 to be integrated with ESS/MSS (HR)

Can anyone help me with the steps to be followed for these integrations as part of SAP security consultant activity?

Thanks & Regards
