If you have Oracle Warehouse Management installed, and you have cartonization enabled for your organization (See: Defining Warehouse Parameters), you can create a category set for grouping contained items and their allowable containers.

An item may be assigned to many cartonization groups. A cartonization group may contain many containers and many contained items. An item is assigned to a cartonization group as either a container or a contained item. See, Cartonization Setup Steps, Oracle Warehouse Management Implementation Guide.
