Migration to SAP S4/HANA without losing your data

The migration to SAP S4/HANA uses a simplified data model, designed to operate in real time. This means that not all legacy data from ECC or previous systems can be migrated directly. A bad management can contaminate the new instance and generate operational failures. In this article you will find tips for a successful migration without losing your data.

Why is data processing key in a migration to SAP S/4HANA?

SAP S/4HANA is based on a simplified data model optimized for real-time processing. This means that not all legacy data from legacy systems such as ECC can be migrated directly. A technical approach is required to ensure:

The right approach ensures:

Purification of obsolete or duplicate data.
Standardization of structures and formats.
Validation of master data (customers, suppliers, materials).
Correct mapping to SAP S/4HANA models and tables.

A migration without rigorous control can contaminate the new instance with erroneous information, generating operational failures and subsequent functional deviations.

Main errors due to bad data migration in SAP S/4HANA

If data quality is not controlled, these are the most common errors:

Functional inconsistenciesas unsuccessful sales orders due to incorrect data.
Reporting problemserrors in reports due to poorly structured data.
Rework and cost overruns: manual validations and post go-live corrections.
Regulatory noncomplianceData migration: poorly migrated data may fail audits.
Integration errorsData not homologated breaks APIs and connectors.

Technical recommendations for a successful migration to SAP S/4HANA

In order to ensure a smooth transition to S/4HANA and avoid critical errors, apply these tips in your SAP S4/HANA migration:

Perform a data quality analysis beforehand with profiling tools.
Establishes cleaning and enrichment rules according to the requirements of the new system.
Implements processes with traceability to record changes between ECC and S/4.
Validates in sandbox or QA environments with real data before going productive.
Involves functional and technical experts in data and business from the start.
