BI Content Administration entries of BO server

Hi

I have installed BI and BO and started integration of BI BO.

My question is.

i am in middle of process like adding entries in transaction /CRYSTAL/RPTADMIN (Content Administration Workbench).

i have given system details and rfc details and also tested the rfc connection its working fine.

now im in HTTP tab and i dont what file path to enter in path content.

web server host is default and port is also default. But the doubt is what is "viewer application"

when i see this viewer application, in default there is one value (reportView.do).

can any one please help me?

thanks
