Thanks for this. The workaround I found was to limit the user role access to view item list only. I didn't realize there was a "current availability" option in the activities button. This reveals quantity by inventory site and whether they are available to sell. The only problem with this method was if there is an incoming quantity on PO, clicking the show details button reveals the name of the vendor below. I know some businesses consider this sensitive information that do not need to be seen by sales staff, so I don't understand why this cannot be blocked in user roles. I had to change each vendor name to a code name.
