item_class

  • Last UpdatedNov 20, 2024

The item_class table defines classes of items, which are used to make specific items easier to find.

The item class table contains all the possible classes (types or groups) of items that are referenced by the system. Typical classes would be Cases, Cartons, Beverage, or Cans in a beverage plant for example. Classes may also be used to distinguish raw materials (component items) and finished goods (parent items).

The ‘obsolete’ field is used to specify that the item or class is no longer usable, but that is not deleted to preserve the context of existing data that references it.
