Dear Sandeep
INbound reports are "special" in comparison to normal WWI reports. Any WWI server need to have the same set up. Normally a pdf file is passed from SAP DMS to WWI server and then back and you will then get only a "print stream"; For normal WWI reports process is "slightly" different
a.) can you display pdf file in CG54 locally?
b.) which set upyou have done in SAP and on WWI server side
c.) Please check the "WWI Cookbook" which is mentioned very often here. By reading you should be able to identify the "set up" error
C.B.
