SAP S/4HANA System Conversion (Brownfield approach) converts an existing SAP ERP ECC system into a fully functional SAP S/4HANA system while retaining historical transactional data, custom enhancements, and business processes. It involves executing SAP Readiness Checks, processing Simplification Item Catalog checks, migrating Customer/Vendor data to Business Partners (CVI), and running Software Update Manager (SUM DMO).
Key characteristics and aspects of SAP S/4HANA Conversion include:
-
SAP Readiness Check & SI-Checks:
- Analyzing system compatibility, active business functions, custom code impact, and add-on readiness.
-
Customer-Vendor Integration (CVI):
- Converting master data tables (KNA1/LFA1) to unified Business Partners prior to technical conversion.
-
Software Update Manager (SUM DMO):
- Executing database migration and software upgrade concurrently using the Database Migration Option.
-
Custom Code Remediation (ATC):
- Remediating non-compatible ABAP code using ABAP Test Cockpit and Quick Fixes in ADT.
SAP S/4HANA Conversion preserves full business history while upgrading legacy infrastructure to modern in-memory standards.
