Go to transaction SE80
>MIME repository>public--> BW there you can create a folder. RMC on the folder and then "Import MIME object". Import your word file.
Now in WAD go to your query and insert this small line in your html tab page. You can do some html thing so as to arrange the link where you want. I had given it the name as REPORT.
<A href="/sap/bw/Mime/public/Customer/YOUR FOLDER/YOURFILENAME.doc">YOURLINKNAME</A>
In the above process the path is important. Let me know if does not work.
