I like scott's article on precise imprecise BOM.
Besides Teamcenter documentation, there is a video on youtube you may want to check out.
Please feel free to post any specific question you may have on this topic.
Scott's is a good one. Mark Hoover also had a good one that he presented on a few years back at http://www.plmworld.org/p/do/sd/topic=197&sid=1126 .
