Parts : Internal Only v8.03

I am wondering if anyone has run across a scenario where only selected
parts could show up in the Part Method Entry Dashboard for selected
users. How is something like this configured?

None of the Parts from any Sales Order would ever be available to view
or edit, for any users that are not-responsible for maintaining
customer parts.

I would not like an individual responsible for ordering shop supplies
to access any Sales Order parts? Currently if anyone does a search in
Part Method Tracker they would have access to view all details of any
Part in the system.
