Diagnosis
Your source system &V1& is not connected to the BW client.

Procedure
We recommend to use trusted RFC connections pointing to the CRM client.Name the RFC connections with suffix "_T" in order to emphasizethe trusted connection property, which lets you easily recognize themwhen needed.
As a result, user log in is enabled without logon screen, because of thetrusted connection. You can test connections using Configuration ofRFC Connections (transaction SM59) and choosing Remote Logon.
