SAP S/4 HANA, the Digital Core,  is the next generation of ERP to modernize for Digital Business. The SAP lines of business solutions continue to be consumed as standalone solutions or as part of the SAP S/4HANA Lines of Business solutions giving more choice to customers, allowing true hybrid scenarios and incremental deployments.

The graphic below shows how we plan to deliver SAP EWM, one of the key SAP Lines of Business Solutions, in combination with the on-premise edition of SAP S/4HANA in two sequential approaches to two separate customer options for product integration on the SAP HANA platform.


Since Q4/2015, SAP EWM has been able to be connected to SAP S/4HANA (on-premise edition 1511, as indicated in the SAP Note 2241931) using a sidecar approach based on the same technology employed for communication with SAP ERP — that is, asynchronous data transfer by qRFC (queued Remote Function Calls) via the CIF (Core Interface) integration layer.

SAP EWM is decentralized deployed on a separate server platform.


The sidecar approach as an option for integration with SAP S/4HANA supports business scenarios and processes of complex and automated warehouse and distribution centers. The two deployment options are SAP EWM as part of SCM Server or deployed on SAP NetWeaver.

In the next step, SAP EWM is planned to be an embedded application component within SAP S/4HANA. The longer-term goal is to have basic warehousing and extended warehouse management running on a common code base embedded in SAP S/4HANA.

The embedded approach as a deployment option within SAP S/4HANA supports less complex or non-high throughput warehouses with a simplified integration to S/4HANA business processes.

      See SAP Note 2494704 – SAP S/4HANA 1709: Release information and restrictions for EWM in SAP S/4HANA.

      This still shows the differences to EWM9.4, I would expect a new one to come for EWM9.5 (which is in restricted release now).
