The option to archive all SKUs would be more beneficial instead of having to delete a parent and archive child items. We currently have many products archived with parents still visible. Occasionally we get previously discontinued stock from suppliers and this is either a pain because we have deleted the parent and need to recreate it or we simply have loads of parents with archived child items.
This is the first system I have ever used where all products (parent and child) cannot be archived or marked as discontinued. The product sort function in an inventory view isn't any help with these.
