Premium Hub CoE – DSC Knowledge Bits – New Migration Guide LE-WM to EWM on S/4HANA

[TamerAdam]

In this blog, I would like to share the latest updates on the new migration guide that was released for supporting customers and consultants during planning the migration from SAP ERP LE-WM or SAP S/4HANA Stock Room Management to EWM on S/4HANA. 

Additionally, I would like to clear up some confusion about end dates of usage rights and mainstream maintenance for SAP LE-WM.

LE-WM Roadmap - Important Dates:
Let's start with the SAP LE-WM roadmap and timeline, as this is mainly dependent on the ERP solution release on which LE-WM is running.

• LE-WM on ERP ECC:
  SAP will provide mainstream maintenance until 31.12.2027 for SAP Business Suite 7 core applications, refer to SAP Note 2881788 for details.
  
  
• LE-WM on ERP S/4HANA:
  SAP restricts the usage of components which are in a compatibility mode until 31.12.2025, refer to SAP Notes 2269324, 2881166, and 2577428 for details.
  
  

Migration Guide Overview:
In this migration guide you will find information about:

• General Process Changes between LE-WM and EWM
• System Setup Guides
• Organizational Structure
• Customizing Settings for Product Master
• Define Handling Unit Management
• Storage Bin Migration
• Putaway and Stock Removal
• Material Master Migration
• Transactional Data Migration
• Stock Migration
• Physical Inventory Completeness Migration

Out of Scope:

• In general, transactional data is not transferred from LE-WM to EWM. So no documents can be open when the migration starts. For more information, see Transactional Data Migration.
• Existing RF transactions are not transferred automatically from LE-WM to EWM.
• System users and the related authorization roles and profiles are not transferred automatically from LE-WM to EWM.
• The existing migration tools do not migrate Customizing. Due to the broader functionality in EWM, the Customizing differs from LE-WM. For more information, see General Process Changes between LE-WM and EWM.
• Customer-specific objects are not transferred
