Course Overview

The SAP Custom Code Migration from SAP ERP to SAP S/4HANA course is designed for ABAP developers and development consultants responsible for transitioning legacy SAP ERP systems to the modern SAP S/4HANA platform. This official SAP training addresses the critical need to adapt custom code due to architectural changes introduced by SAP HANA and the simplification initiatives in SAP S/4HANA. Participants will prepare for challenges associated with the SAP S/4HANA migration, focusing on identifying and resolving compatibility issues. With over 68% of organizations reporting a talent shortage in S/4HANA migration expertise, this course equips professionals with in-demand skills essential for a successful system conversion.

This course provides hands-on experience with key SAP tools essential for custom code analysis and remediation. Students will work directly with the Custom Code Migration App, ABAP Test Cockpit (ATC), Code Inspector, and SAP Fiori-based analysis tools within a connected on-premise and cloud environment. The lab component involves configuring remote checks between an on-premise SAP ERP system and a central ATC check system in the SAP Business Technology Platform (BTP) ABAP environment. A core project requires learners to perform a comprehensive SAP S/4HANA readiness check, analyze findings from the simplification list, and execute the remediation of code affected by field length extensions and obsolete database operations.

Completing this course prepares learners for SAP's official certification paths related to S/4HANA implementation and positions them for roles in the high-growth SAP BTP and S/4HANA consulting space. SAP ABAP/RAP developers are in significant demand, with median salaries reaching $131,000 in the US market. Koenig Solutions enhances this learning with its Guaranteed-to-Run promise and access to official SAP courseware, ensuring a reliable path to skill mastery. By gaining expertise in custom code migration, professionals secure a critical role in the multi-billion dollar global effort to modernize enterprise resource planning, paving the way for careers as S/4HANA Solution Architects or specialized migration consultants.
