Clearly content links will not synch the WTpart BOM.
So if you use any downstream app like MPMLink... your eBOM will not be reliable ... No tools to compare CAD structure and WTpart BOM without owner link ....
but you can disable the automatic build for owner link (which synch and iterate the WTpart automatically when the CAD iterateby setting the preference "build.after.check.in" to NONE (Site, Org or Container level)
windchill wt.preference.SetPreferenceUtility -u wcadmin -p wcadmin -name build.after.check.in -value None
windchill wt.preference.SetPreferenceUtility -u wcadmin -p wcadmin -name build.after.check.in -value None -container /wt.inf.container.OrgContainer="Demo Organization"
windchill wt.preference.SetPreferenceUtility -u wcadmin -p wcadmin -name build.after.check.in -value None -container "/wt.inf.container.OrgContainer=Demo Organization/wt.pdmlink.PDMLinkProduct=GOLF_CART"
windchill wt.preference.SetPreferenceUtility -u wcadmin -p wcadmin -name build.after.check.in -value None -user wcadmin
You are the able to synch the WTpart (attributes, viz and structure) asynchroneously "on demand" with the CAD to Part compare tool in the action menu of the CAD info page
