Good afternoon, I am trying to pull these Hazmat fields on a Item Search, but for some reason I cannot find them. It looks like they are part of a Fedex shipping feature. • Any ideas why? Thank you in advance.

potentially a permissions issue. Are you logged in as admin? Are you able to go into the field definitions (Customization > Lists, Records, & Fields > Item Fields) and see what's under the "Access" tab?

I really have no idea. These are not Custom fields. I cannot pull them on a Search and when I try to show them using a formula it errors out.
