This implementation guide is established by the META project and addresses the implementation of the GS1-defined Transport Status transaction which is implemented by means of two messages: Transport Status Request and Transport Status Notification. These messages support status reporting on transport instructions and associated transport operation executions. The report has a technical and a logical part. In the technical part the structure and the content of the messages are defined. In the logical part a scenario illustrates how the messages are to be used, and answers to frequent asked questions are provided together with message content examples.
