Hi Indu,
Can you please try with S-User ID which has sufficient authorization? I don't have authorization to see SAP TM TT RDS documents in my S-User ID however can you please navigate till <DVD>\SAP_BP\BBLibrary\Documentation ? Once you navigated to "Documentation" folder just open the word documents and see the title of the document.
You have to find out "Connectivity (PI)" from the list. I will see whether I can attach the file here.
Thanks,
Pradeep
