The speedy and efficient exchange of information between supply chain partners is of paramount importance in the fast moving environments experienced by many enterprises. Thanks to the open nature of Tropos and its extensive integration capabilities, EDI messages can be received and processed automatically, with outgoing messages being generated in response to certain events. In this way, sales orders can be received, validated and recorded without human intervention, with any validation errors or discrepancies being highlighted for review. The sales orders raised are identical in form to those entered by hand, ensuring a consistent order processing procedure. On dispatch, EDI messages covering invoice and advance shipping note information can also be generated automatically.
