Answer 1

Before proceeding further, the following tests will confirm whether all entries in your RFC connections are correct and no issue.
on R/3: test connection & authorization for your RFC connections
SM59->R/3 Connection->select your R/3 RFC connection ->'Test connection'
SM59->R/3 Connection->select your R/3 RFC connection ->'Test' menu ->'Authorization'
Do the same for your BW RFC connection
On BW: test connection & authorization for your RFC connections
SM59->R/3 Connection->select your R/3 RFC connection ->'Test connection'
SM59->R/3 Connection->select your R/3 RFC connection ->'Test' menu ->'Authorization'
Do the same for your BW RFC connection
If connection test and authorization tests are successfully; you can proceed with creating souce system.
If failed, troubleshoot to see where the error is. Your Basis can assist with test connection failed and Security can assist with Authorization test.
