When you send a delivery proposal to SAP ERP, the SAP TM system sets a send timestamp in the freight units to which the delivery proposal relates. When SAP ERP sends a confirmation of delivery creation, the SAP TM system sets a confirmation timestamp in these freight units. If delivery creation is successful, SAP ERP also sends a request to create a delivery-based transportation requirement (DTR), and the SAP TM system reassigns the freight units from the order-based transportation requirement (OTR) to the DTR.
To monitor the delivery creation process, SAP TM checks whether freight units contain a confirmation timestamp and whether they have been reassigned from an OTR to a DTR.
