Erik,
I see that you are on Windchill 10.0 - but maybe the easiest is an update to 10.1 where there is the Relationship Explorer: http://communities.ptc.com/servlet/JiveServlet/showImage/38-2227-30209/Easily+view+interconnected+product+information+with+the+Relationship+Explorer.png
Since this is a new feature don't expect something too polished regarding printing etc. But depending on the size of your BOMs I guess a screenshot or two might do the job.
Cheers,
Jorn
