You can use the Structure Manager in Teamcenter and bring up both BOMs and run a compare.
Thank you Scott. I have one BOM in precise from the product I want to compare. How can I find a similar structure with the last revisions to compare to?
You would need to do this in Teamcenter in Structure Manager. You can bring up two BOMs, once configured precise and the other with lastest working and then run the compare on them.
You could use Visual Reporting. There is an OOTB report called Has Higher Revision that will highlight any components or sub assemblies that have a later revision.
