This process is based on SAP ERP sales orders and outbound deliveries. It involves transportation planning in SAP EWM followed by ERP-TM shipment integration. Shipments are transferred to SAP TM to perform charge calculation and freight settlement.
The following is an example of how you can integrate SAP TM, SAP ERP, and SAP EWM. Variants of this process are possible.
You have made the required settings for the following:
Integrating SAP ERP with SAP EWM. For more information, see SAP Library for SAP EWM on SAP Help Portal at http://help.sap.com/ewm. In SAP Library, choose .
Integrating SAP ERP shipment processing with SAP TM. For more information, see the relevant settings in Shipment-Based Tendering.
The figure below shows the integration of SAP ERP outbound deliveries with SAP EWM transportation planning and SAP TM charge calculation and freight settlement. The figure is followed by a description of the process:
Create outbound deliveries for sales orders (SAP ERP)
SAP ERP sends outbound deliveries to SAP EWM. The outbound deliveries are based on SAP ERP sales orders and have been created without ERP-TM order and delivery integration.
Create outbound delivery requests and outbound delivery orders (SAP EWM)
SAP EWM creates outbound delivery requests and outbound delivery orders based on the SAP ERP outbound deliveries. Outbound delivery orders form the basis of warehouse activities in SAP EWM.
Create transportation units (SAP EWM)
SAP EWM creates transportation units and assigns the outbound delivery orders to the transportation units.
Perform transportation planning and warehouse planning and execution (SAP EWM)
SAP EWM plans the transportation of the goods, and plans and executes the required warehouse activities (for example, picking, packing, staging, and loading).
Post goods issue (SAP EWM)
When the goods issue is posted, SAP EWM sends confirmed execution results to SAP ERP (for example, packaging of deliveries, and actual quantities and weights).
Create shipments (SAP ERP)
Based on the warehouse execution data, SAP ERP updates the outbound deliveries and creates the required shipments. SAP ERP assigns the outbound deliveries to the shipments and transfers the shipments to SAP TM.
Create freight orders (SAP TM)
SAP TM automatically creates freight orders based on the shipments.
Perform charge calculation and freight settlement (SAP TM)
When the transportation activities have been completed, charge calculation and freight settlement can be performed in SAP TM. Freight settlement forms the basis of invoice verification and settlement in SAP ERP. For more information, see Charge Calculation and Freight Settlement.
