FAQ: What you need to know about SAP EWM
What is an SAP EWM implementation and integration partner?
An SAP EWM implementation and integration partner is a company that supports customers in designing, implementing, and integrating SAP Extended Warehouse Management (EWM) within their warehouse landscape.
This typically includes:
- Configuring SAP EWM within SAP S/4HANA or decentralized EWM environments
- Implementing warehouse processes (inbound, outbound, internal movements)
- Integrating automation systems using SAP EWM MFS or standard interfaces
Swisslog is an SAP service and implementation partner, specializing in end-to-end integration of SAP EWM with warehouse automation systems such as conveyors, AS/RS, shuttles, and robotics. With its combined expertise in SAP software and intralogistics automation, Swisslog delivers fully integrated warehouse solutions from software design to physical system integration.
What are the main strategies for migrating from SAP WM to SAP EWM?
The three main approaches are greenfield (a new S/4HANA implementation built from scratch), brownfield (an in-place system conversion that preserves existing data and configuration), and Selective Data Transition (a hybrid migration that moves selected data into a new environment). The right choice depends on the level of custom development and processes in the existing system, the complexity of automation interfaces, and the organisation's appetite for process redesign.
Can SAP WM still be supported after 2027?
SAP's extended maintenance for SAP Warehouse Management ends on December 31, 2027. After that date, no security patches, regulatory updates, or technical support will be provided by SAP. Third-party maintenance providers may offer continued support, but these arrangements do not address the underlying limitations of the platform — particularly its inability to integrate natively with SAP S/4HANA or modern automation systems.
What are the recommended steps of an SAP WM to EWM migration?
A structured migration typically follows six steps:
- Current-state assessment — Analyse existing SAP WM processes, custom developments, interfaces, and automation integration.
- Migration strategy definition — Select greenfield, brownfield, or selective transition based on business and IT goals.
- Master data preparation — Cleanse and harmonise material, warehouse, and business partner data.
- Solution design & interface setup — Redesign warehouse processes and redefine integration with ERP and automation systems.
- Testing & validation — Execute integration, user acceptance, and performance tests to ensure operational readiness.
- Cutover & go-live — Transition to EWM with structured cutover planning, monitoring, and hypercare support.
How long does an SAP WM to EWM migration take?
The duration depends on system complexity, automation level, and migration approach.
Typical timelines are:
- For a greenfield project: ~12–24 months
- For a brownfield project: ~9–18 months
- With a selective data transition: ~12–20 months
Key influencing factors are:
- Number of warehouses and processes
- Degree of automation integration
- Data quality and system landscape
- Business readiness and change management
What should we do now to prepare for an SAP WM migration?
To enable a smooth transition to SAP EWM, organisations should prepare early:
- Stabilise the current system
Avoid new custom developments in SAP WM - Document system landscape
Capture warehouse processes, interfaces, and automation integrations - Cleanse and standardize master data
Improve data quality for migration readiness - Review automation integration
Assess current control systems and future integration via SAP EWM MFS or middleware - Define target architecture
Align on embedded vs. decentralized EWM and S/4HANA strategy - Start partner evaluation early
Select experienced SAP EWM and automation integration partners
