System controls for electronic data interchange.
June 1989 System controls for electronic data interchange. EDI networking eliminates the paper trail that was the cornerstone of the traditional audit and has made certain controls obsolete. Generally, in an EDI environment, an on-line communication network links the computer systems of a given vendor and its customers. A customer can place an order through the EDI network to a vendor's system, thus avoiding some clerical paperwork and saving the time required for postal delivery. After receiving the order through the network, the vendor can acknowledge the order, issue a delivery notice, and dispatch an invoice through the same network.
