Order-Based Transportation Planning (Outbound) 
In SAP Transportation Management (SAP TM), you can plan your transportation activities based on an order and send your freight orders to SAP Extended Warehouse Management (SAP EWM). In SAP EWM, you can then 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.
Prerequisites
For more information, see Direct Integration with SAP Extended Warehouse Management.
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
Create a sales order in SAP ERP and send it to SAP TM. In SAP TM, an order-based transportation requirement is automatically created along with the associated freight units.
Transportation Planning in SAP TM
Plan your transportation activities by creating a freight order based on the freight units created in the previous step.
Generate delivery proposals and send these to SAP ERP. Outbound deliveries are created in SAP ERP based on these delivery proposals. They are then transferred to SAP TM and the delivery reference is added automatically to the freight order. The delivery reference is displayed in the document references for the item.
When you have finished planning your transportation activities, 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.
NoteIn this step, the system checks whether outbound deliveries have already been created. The system can change the status and send the message only if outbound deliveries have already been created.
End of the note.
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 following functions are supported:
The warehouse workers can load deliveries from other freight orders onto the truck if the truck has some free capacity. If an entire delivery does not fit onto a truck, you can load some of the delivery. For more information, see Delivery Split.
The warehouse workers can pack an item into different handling units. If the entire quantity cannot be delivered, they can split the item.
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 order-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.
If you have loaded deliveries from a different freight order as described in step 4 under "Execution in SAP EWM", the system automatically changes the assignment of the corresponding freight units. This means that these freight units are removed from the other freight order and assigned to your freight order.
If the warehouse workers have packed an item in different handling units in EWM, the items for these handling units are created automatically in SAP TM. The handling units then contain the subitems of these packaging items, which can be either product items or packaging items with subitems (nested packaging hierarchy).
