The difference between "Open" and "Barred" is that barred products are not open for sale; it will not be possible to add the products to Offers, Orders, Invoices etc., where else open products can be added and sold.
Barring is often used as an alternative to deleting a product, because it is not possible to delete a product in Rackbeat that has had inventory transactions.
It is possible to hide barred products from the product overview by changing "Status" within the filter function to "Open" (press "Remember" to the right of the search field if you want to save this setting).
