Transportation and Shipment Scheduling in TP/VS
Use
The Transportation Planning/Vehicle Scheduling (TP/VS) component uses transportation and shipment scheduling in SAP APO. The following only deals with the points that are relevant for TP/VS. For general information about transportation and shipment scheduling in SAP APO, see Scheduling .
Features
Transportation and shipment scheduling for sales orders
If in TP/VS you trigger the generation of deliveries in SAP R/3 for the sales orders for which you have created planned shipments, SAP APO determines the following five dates:
Delivery date
Goods issue date
Loading date
Material availability date
Transportation planning date
Three of these dates result from the transportation activities that you generated in TP/VS. They are transferred automatically to SAP R/3 when you trigger the generation of deliveries:
The delivery date corresponds to the start date of the unloading activity.
The goods issue date corresponds to the end date of the loading activity.
The loading date corresponds to the start date of the loading activity.
The SAP APO system schedules the material availability date and the transportation planning date when you trigger the generation of deliveries in SAP R/3 from TP/VS. The SAP APO system schedules the dates using backward scheduling from the loading date. The SAP APO system uses the times you defined in the Customizing for transportation and shipment scheduling as a basis.
If the SAP APO system determines that one of these five dates is in the past, it does not transfer the dates. The transportation and shipment scheduling occurs when the deliveries are created in SAP R/3.
Scheduling for stock transfers
For stock transfers, the delivery date, the goods issue date, and the loading date also result from the transportation activities. The SAP APO system calculates the material availability date and the transportation planning date using backward scheduling and starting from the goods issue date. For this to happen, you have to define the following values:
Goods issue time in the product master record
The system then calculates the material availability date as follows:
Goods issue date – goods issue processing time = material availability date
Shipment creation time in the location master of the start location.
The system then calculates the transportation planning date as follows:
Goods issue date – shipment creation time = transportation planning date
Shipment calendar in the location master of the start location
If the SAP APO system determines that one of these five dates is in the past, it does not transfer the dates. The transportation and shipment scheduling occurs when the deliveries are created in SAP R/3.
Transportation and shipment scheduling for purchase orders
For purchase orders, the SAP APO system only transfers the delivery date to SAP R/3.
Note
If the TP/VS dates that you have already transferred to SAP R/3 change, for example due to the rescheduling of a shipment, you can synchronize them in SAP R/3. For additional information, see Changing Delivery Dates/Times in SAP R/3 from TP/VS .
