In addition to the implementation of DMS4.0, another major change awaits licensees IIAA: DMS4.1. After recent consultations with many of our customers, we came to the conclusion that the logistics world still has many questions about the topic. Especially the procedure regarding the delivery notice and the subsequent additional declaration raises quite a few questions. Our information session on April 19, 2023 in the vintage cinema rooms of Lab1 in Eindhoven, has undoubtedly already provided those present with more insights. Through this new Stream Story, we want to inform you to further share our already acquired knowledge with you by means of a white paper that can be downloaded below. We start with some definitions and theoretical concepts, and will continue in this Story with some practical example flows. It is quite a read! We try to add to this document as new developments or information becomes available.
