What's new? The technological bridge between public cloud and private cloud
The core of the new solution is the "SAP EWM for SAP S/4HANA Integration (7L1)" integration scenario, which is activated via the SAP_COM_0A58 communication scenario. It allows the synchronization of transaction data between the public cloud ERP and a decentralized EWM system in the private cloud or on-premise.
For this to work, you need:
- at least the SAP S/4HANA Cloud Public Edition 2508
- on the EWM side either:
- SAP S/4HANA Private Cloud Release 2023 FPS0, if no batch master data distribution is required,
- or FPS3, if you use batch distribution via DRF (Data Replication Framework).
Which processes are covered?
With the new integration, you can map a large number of important warehouse processes in SAP EWM, including:
- Goods receipt from supplier
- Outgoing goods to the customer
- Production supply & goods receipt
- Customer returns
- Batch management - including creation in both systems
- Stock transfer orders
These processes are supported by clearly defined scope elements that SAP is continuously developing.
What needs to be considered when setting up the technical equipment?
The connection between the public and private cloud is established via the SAP Cloud Connector and WebSocket communication. In addition to configurations in both systems, cutover activities and customizing settings are also required. SAP provides detailed setup instructions that explain the process step by step.
Supported application scenarios
In the first step, SAP supports the integration of an SAP S/4HANA public cloud client (with or without cloud warehouse management) with an EWM system in the private cloud.
Important: EWM in the private cloud may only be used as a decentralized warehouse management system. The integration of several SAP ERP systems into an embedded EWM is not intended.
Limits of integration - what you should know
Despite the new possibilities, there are functional limitations that you should be aware of:
- Handling units are managed exclusively in EWM and are not transferred to the public cloud
- Serial numbers at warehouse level B (complete history per storage bin) are not supported in the public cloud
- Classic transport integration via LE-TRA and integration with SAP Transportation Management (TM) are currently not available
SAP Note 3629180 provides a complete overview of these restrictions, which you should definitely include in your planning.
Conclusion: More flexibility for complex logistics processes
The integration of SAP S/4HANA Public Cloud with a decentralized EWM in the private cloud opens up new perspectives for you as an SAP user: you remain flexible on the way to the cloud, benefit from standardized ERP processes in the Public Edition and at the same time have the opportunity to manage complex warehouse requirements professionally.
The combination of both - the scalability of the public cloud and the performance of decentralized EWM - is a strong argument for companies looking for the best of both worlds in the hybrid world.
