I'm linking Webi Documents SAP BusinessObjects XI 3.1

A example of my hyperlink is

http://stjh1482:8080/OpenDocument/opendoc/openDocument.jsp?iDocID=5935&sType=wid&sRefresh=Y&sWindow=New&lsSmem=([Assignment-Member])&lsSfy=([Fiscal Yr])&lsSgrp=([Assignment-Group])&lsSttype=([Type])

Is there anyway to make the server name and docid a varible?

I need this because I want to move it from a dev to prod  Environment anf don't wamt to edit every link.

Thank you
