Since trace link can be used for link everything, not only requirements, we want to use it to link drawing to part. They are both customize item types in our Teamcenter. we link item revision to an item revision.
When I send an assembly to SM, open a trace link view, the Excel export button is greyed out. However, in the My Teamcenter prospective, open a trace link view, I can use the button to export to excel.
I don't know the reason why it behaves like this. The figure is shot in the Structure Manager. it is grey out.
