- /WM-to-EWM Readiness Assessment
Understand what a WM-to-EWM migration actually involves before you commit to one.
A structured assessment of your current WM landscape, the realistic gaps against SAP EWM, and the risks and roadmap options for the migration — before scope and budget get locked in.
Who this is for
You're planning an S/4HANA transformation and need to decide how warehouse execution fits into it
You're running classic Warehouse Management and it's approaching end of mainstream support
Your warehouse landscape needs rationalising across multiple sites or systems
You're unsure whether Stock Room Management or full SAP EWM fits your production supply process
Your current WM setup has complex custom interfaces you don't want to migrate blind
Your warehouse already depends on automation equipment that any migration has to account for
Questions we help answer
- What in our current WM configuration and custom code actually needs to be rebuilt in EWM, versus what EWM already covers natively?
- Should we run embedded EWM inside S/4HANA, or a decentralized EWM deployment — and what does that decision actually hinge on?
- Does Stock Room Management cover our production supply scenario, or do we need full EWM?
- Which of our existing interfaces, IDocs and APIs need to be redesigned rather than just re-pointed?
- What's the realistic risk profile of this migration, and where are the points most likely to slip?
- How does our automation and RF estate constrain the migration approach?
- What would a phased migration roadmap look like for our landscape specifically?
What we assess
The assessment is scoped to your landscape — not every area below applies to every engagement.
- Current WM processes and configuration
- Warehouse structure and storage strategy
- Custom developments (user exits, BAdIs, Z-transactions)
- RF transactions and device estate
- Interfaces, IDocs and APIs
- Automation and WCS dependencies
- Master data quality and structure
- Operational constraints and migration dependencies
Approach
Discover
Review current WM configuration, custom objects, interfaces and operational context.
Analyse
Map current-state capability against SAP EWM standard functionality, identifying real gaps.
Challenge
Stress-test assumptions on deployment model, automation dependencies and migration sequencing.
Recommend
Deliver a target architecture, risk register and a prioritised, phased migration roadmap.
Typical deliverables
Deliverables are scoped per engagement — not every assessment includes every item below.

Why ERP Factory
- We specialise in SAP EWM and warehouse execution — this is not a generalist S/4HANA workstream to us
- Senior architects who have implemented EWM lead the assessment, not a templated questionnaire
- We assess the automation and integration layer alongside the SAP configuration, not as an afterthought
- The recommendation is scoped to what your landscape actually needs, not a maximal target architecture by default
