The activity we execute during the sales process are reflected in the system in a number of documents. For example, the quotation, the order, the delivery and the invoice. Such documents are logically chained within the Document Flow.

In frequent cases, a new document is created as subsequent of a previous document. For example, a sales order can be subsequent of a quotation. Every time this happens, part of the information in the previous document is copied to the subsequent document, in addition some updates are executed in the previous document.
