Clicking "Open as CSV file" on the Contains Tab of an assembly shows a field/column called "Level" on the left by default. I want to add this same "Level" information to my BOM view so that the "Leve" field/column appears when I extract the BOM in excel using the "Open As CSV file". Does anyone know how to do that?

I tried adding the "Level" variable to my BOM view but it doesn't do it. The "Level" fiels are empty (in the BOM tab and in excel).

Thanks for your help!
