AI-Assisted Custom Code Migration for SAP S/4HANA

Client Overview

SAP Labs India, headquartered in Bangalore, is SAP’s largest R&D center outside Germany. With its deep focus on innovation, SAP India leads the global development of critical enterprise solutions—including the flagship SAP S/4HANA platform.

As part of SAP’s vision to accelerate cloud migration and modernize enterprise IT stacks, the team sought to streamline custom code migration from ECC (ERP Central Component) to SAP S/4HANA for its developer ecosystem.

The Challenge

Custom code migration from SAP ECC to S/4HANA is a highly complex and resource-intensive task due to:

  • Massive legacy codebases with interdependencies
  • Incompatibilities in syntax, APIs, and data models
  • Risk of system downtime and regression bugs
  • Slow and manual code reviews that delay go-lives

SAP’s internal developer teams needed a solution to automate and optimize the migration process while ensuring high code quality, compatibility, and performance in S/4HANA environments.

MSITEK’s Solution

To address these challenges, MSITEK collaborated with SAP Labs to design and implement an AI-powered Custom Code Migration Assistant, integrating cutting-edge SAP and AI technologies:

Key Capabilities Deployed:

  • AI-Powered Code Analysis
    • Leveraged SAP Joule AI Assistant to scan and interpret legacy ABAP code.
    • Used LLMs (Large Language Models) for semantic code understanding.
  • Automated Code Transformation
    • Integrated the CCM (Custom Code Migration) App on SAP BTP for dependency analysis and migration scoping.
    • Applied ABAP Test Cockpit (ATC) and Quick Fixes for auto-adapting deprecated functions and data structures.
  • Predictive Quality Scoring
    • Built a machine learning layer that scored migrated code for stability, compatibility, and performance.
  • Developer Workflow Integration
    • Embedded the assistant directly into the SAP developer workspace, using SAP OData APIs for seamless interaction.
