Advanced supply chains with SAP Extended Warehouse Management – “Direct loading of finished goods”
within one of my last projects we have implemented a factory outbound process with SAP Extended Warehouse Management (SAP EWM) which allows customers to build stock transfer orders dynamically based on the production output. I am happy to share this process with you today.
The production sites and the warehouses are in different locations and shuttle trucks are used to carry the finished goods from production sites to the warehouses.
The sequence of the finished goods is not predictable and the production sites have very limited space for storing finished goods in the outbound. Therefore planning of the stock transfer and the shuttle truck loads is not possible. It is required to build the shuttle truck load dynamically during loading the trucks.
The following picture illustrates the business process:
SAP EWM – Direct Outbound Delivery to Another Plant
SAP EWM is able to create direct outbound deliveries. These deliveries are sent to the connected enterprise management system (SAP ERP or SAP S/4HANA).If the goods recipient of the direct outbound delivery is not assigned to an external customer but to another plant in SAP S/4HANA or SAP ERP a stock transfer order (STO) is created first followed by a replenishment delivery with reference to the STO.
And… quantity changes, new items or deleted items in EWM automatically update the stock transfer order and the outbound delivery in SAP S/4HANA or SAP ERP.
This function is used to fulfill the business requirement.
The SAP EWM process creates the stock transfer order dynamically. Whenever a pallet is loaded to a truck the system assigns the corresponding handling unit to the existing outbound delivery in SAP EWM which automatically updates the STO and the outbound delivery in SAP S/4HANA or SAP ERP
The following picture illustrates the document flow between SAP EWM and SAP S/4HANA.
It’s simple to run this process in SAP EWM. The process starts with a handling unit which is ready for loading and goods issue. Therefore the HU should not have reference to an inbound delivery and it should be located within a storage type that allows goods issue posting (storage type settings).
Use the business partner which is used as customer number of the receiving plant as ship-to-party. You can check the business partner in table T001W for example.
The last step is the assignment of the handling unit to the direct outbound delivery order. You can do this on the handling unit tab using the function “Create”. Enter the handling unit and the item type you want to use e.g. the standard item type “OPPG” (Packaging Outbound Delivery without picking).
When you save the direct outbound delivery SAP EWM immediately sends a message to the connected enterprise management system (SAP ERP or SAP S/4HANA) to create a stock transfer order and an outbound delivery.
The following SAP S/4HANA / SAP ERP function modules are used. They are called as queued remote function calls (qRFC).
Create stock transfer order: /SPE/CREATE_STO_FOR_DIRDLV
Create outbound delivery: /SPE/DELIVERY_CREATE_FROM_STO
Whenever you update the direct outbound delivery order in SAP EWM the stock transfer order and the outbound delivery are updated as well e.g. in case of additional handling unit assignments.
A further business benefit is the capability of the stock transfer order process to take over the packaging data from the outbound delivery to the inbound delivery. This enables a complete automatic inbound process in the receiving warehouse – even without manual interaction if warehouse automatization is used.
The described process is available for the following deployments:
- Decentral SAP EWM connected to SAP S/4HANA
- Decentral SAP EWM connected to SAP ERP
- SAP EWM embedded in SAP S/4HANA
Customer specific RF transaction
To enable the loading stuff to work only with mobile devices a customer specific RF transaction was built based on the RF framework to assign handling units to an outbound delivery by scanning a handling unit and a door.
The direct outbound delivery to another plant process in SAP EWM and S/4HANA/SAP ERP enables our customers to fully automate the supply chain between factories and distribution centers.
It allows to dynamically built the shuttle truck loads without the need to plan the stock transfers in advance. This is relevant in particular if the exact sequence of the finished products of a factory is unpredictable and if there is no space to store the finished goods in the outbound area of a factory.
