Data migration techniques
Methods for transferring data and structures from the LE-WM module to SAP EWM.
CSV transfer
- Intermediate CSV files - exporting and importing data via intermediary files between systems
- Data quality control - verification and mapping of data before loading into SAP EWM
Migration tools
- Dedicated migration tools - ready-made SAP programs for transferring data and structures
- Transfer automation - a repeatable, controlled migration process for large volumes, supported by modern tools (e.g., UiPath).
RFC communication
- RFC connection - direct, automatic data exchange between systems
- Transfer without intermediary files - moving data directly through the RFC interface, without intermediate files.
Migration
We divide the migration process from LE-WM to SAP EWM into six steps - from system preparation and structure transfer, through master data and stock migration, to consistency checks and operational go-live.
Preparation
We configure RFC connections and structures in the target system.
Warehouse layout
We transfer storage types and sections using an SAP tool.
Master data
We migrate products and warehouse parameters to SAP EWM.
Data cleansing
We close open deliveries and orders in the LE-WM module.
Stock and bins
We perform a bulk transfer of locations and stock levels.
Go-live
We check data consistency and bring the system into operational use.
