integration bi 7 portal 6 error : rswr_rfc_service_test

Hello,

I try to integrate BI 7.0 in EP 6.0 SP15 but I have an error in SPRO at Step 12 : System failure during call of function module RSWR_RFC_SERVICE_TEST

But I applied the note 937697 : Usage of SAP NetWeaver BI Diagnostics. And everything is green.

I looked at the note 888687 but the errors do not match.

Should we install a component for BI on EP 6.0 ?

Thank you for your help !
