The product library should have a view and edit function. The sales team occasionally needs to see data kept in the product (shipping conditions, scaled pricing etc which can be kept in notes) but if they don’t have access to Edit the file they can’t see any of the properties.
Secondary there is an issue with the use of the product library when creating quote. You can only search by name. Surely SKU is an equally reasonable way to search? It seems like the search function should take both of these fields into account.
