An item type is a classification of the components that make up a workflow process. You must associate any component that you create for a process, such as a function activity or a message, with a particular item type. Often it makes sense to define an item type so that it describes the item being managed by your workflow process. For example, purchase order requisition can be an item type while a purchase order requisition identified by a particular ID number is an item of that item type. See: To Create an Item Type.
