Summary
Certified SAP-PM/EAM Consultant, self-employed with a focus on S/4HANA data migrations. I cover the full range of migration services: SAP PM/EAM module and process consulting, data preparation/ETL with KNIME, including the definition of migration objects, mapping and field requirements, as well as the technical execution of migrations using the Migration Cockpit (staging tables), including adapting migration objects with LTMOM. For migration projects in other SAP modules, I handle the technical migration and, when needed, the initial data preparation—in close coordination with the module consultants responsible for the business side.
- Developed automated workflows for data preparation, reducing migration time from days to minutes
- Migrated a large volume of data to SAP S/4HANA, including 150.000+ technical objects, 16.000+ maintenance items, 50.000+ notifications, and other related master data
- Ensured go-live readiness through end-to-end User Acceptance Testing (UAT)
- Created functional specifications for developing user-friendly Fiori apps to manage maintenance plans/items and orders, significantly reducing manual effort and increasing user acceptance
