The document system can contain several different document definitions that are closely linked, for instance a business process. The Document System is an entity that separates document data from other Document Systems.
A document system can be made up of several document definitions. These document definitions can be linked to each other so that continuous steps can be made. This means, for instance, that filling out a receipt ticket can lead to the creation of a financial obligation.
Example: the purchase document system that organizes all the steps of the purchase process in the shape of documents.
