There is no permission to just view products.
If you want allow staff to view additional details of a product you must allow them to edit products.
You have view and edit on just about all other areas of the system apart from one of the most important and obvious parts of the system.
This is really bad. This is one of the most important areas and you allow any person to edit the data. We have had warehouse staff change product details and cause all sorts of havoc.
we have got the same issue, this also goes into the client permissions as well.
i have raised this on MST-I-754
