Outbound-Delivery-Based Transportation Planning 
In SAP Transportation Management (SAP TM), you can plan your transportation activities based on an outbound delivery and send your freight orders to SAP Extended Warehouse Management (SAP EWM). In SAP EWM, you can carry out the steps relating to the warehouse, for example, loading. Because the two systems are directly integrated with one another, SAP TM informs you that the truck in SAP EWM has been loaded and whether there are any discrepancies such as quantity deviations.

Process
A sample process for one transportation stop is described below. If your freight order comprises several transportation stops, the process is repeated for each stop if the stop contains loading locations relevant to SAP EWM. Note, however, that multiple pickup and multiple delivery scenarios are not supported.
Preparation in SAP ERP
You create a sales order in SAP ERP.
You create outbound deliveries in SAP ERP and send them to SAP TM and SAP EWM. In SAP TM, a delivery-based transportation requirement is automatically created along with the associated freight units. In SAP EWM, an outbound delivery request and an outbound delivery order are created automatically.
Transportation Planning in SAP TM
You plan your transportation activities. When you do so, you create a freight order manually or the system creates one automatically.
You set the cargo execution status of the freight order to Cargo Ready for Loading. The system automatically sends a loading instruction to SAP EWM with the message LoadingAppointmentRequest.
Execution in SAP EWM
When the LoadingAppointmentRequest message is received from SAP TM, SAP EWM automatically creates a transportation unit.
Picking is carried out by the warehouse workers. The system can create handling units automatically.
When the truck arrives at the yard, the warehouse workers report its arrival and assign a door to it.
The warehouse workers load the truck.
The warehouse workers post the goods issue (optional).
The warehouse workers post the departure of the truck. SAP EWM sends the LoadingAppointmentNotification message to SAP TM. At the same time, the outbound delivery is automatically updated in SAP ERP.
Update and Further Steps in SAP TM
When the data is updated in SAP ERP, the delivery-based transportation requirement is automatically updated in SAP TM.
When the LoadingAppointmentNotification message is received, SAP TM updates the freight order and sets the execution status to In Execution. The cargo receipt status at item level is automatically set to Shipped. If the item in question is to be unloaded at the next transportation stop, the handling execution status is automatically set to Not Unloaded. The system also updates the associated freight units.
You complete freight order execution.
