The vault does not necessarily have the same management of the display of bills of materials as those built in SW. But in order to be able to extract the data and test to get what you want, you need to set up the nomenclature to display the columns you are interested in in the administration interface. The export is then done directly in the windows exporter of the vault (nomenclature tab).
Cegid had also developed a module (10 years ago) that scans solidworks assemblies and allowed the component list to be imported directly into the BOM. That's what we use now (but we didn't have PDM at the time).
I would be interested to know how you reuse the PDM export to generate the bill of materials in Cegid.
The mill developed 10 years ago by Cegid is no longer really maintained and there is a risk of getting stuck during a Cegid or Solidworks update
