3. Item Classes: Defined

Item classes are a way of grouping together item types in order to further simplify and expedite searches in the PRT database.

 Important: Although item types do not have to belong to an item class, it is strongly recommended that you create item classes. You can create just one item class to which all of your item types can belong.

Item Classes:

Group item types together to create a larger subset in the database.

Are independent of region, group or service.


The item types in the previous example are grouped into four major classes, creating an organized and logical hierarchy of information.

The following chart demonstrates how you can create item classes based on defined item types.
