The document outlines eight essential steps for an efficient data migration when moving to SAP S/4HANA: 1) Prepare by defining roles, systems, and schedules. 2) Extract data from source systems. 3) Profile the data to analyze and cleanse it. 4) Design a blueprint for the target SAP S/4HANA data. 5) Map the data fields between source and target. 6) Construct the data by enriching it manually. 7) Transform and validate the data loading process through simulations. 8) Load the data into SAP S/4HANA. Following these steps helps ensure a proper data migration and optimized transition to SAP S/4HANA.

• Empower business users to look after their data
• Allow users to find and fix data from one location
• Enable business users to quickly identify and remediate data
Key Success Factors
• A governance structure that simplifies data validation
• Data that is dynamically linked to the target data design
• Business validation of data enrichment
• Ability for business users to easily complete data enrichment
