The Document Type defines the routing definition and other properties for a set of documents. Each document is an instance of a Document Type and conducts the same type of business transaction as other instances of that Document Type. Document Type is used to distinguish between the different types of transactions or maintenance actions possible in the KC as well as transactions that can be fed from external systems. A separate Workflow Document Type defines the routing behavior of KC documents.
A Document Type may be part of a hierarchy of Document Types, each of which inherits certain properties of its Parent Document Type.
