At a glance

Formated Description

A global consumer electronics brand partnered with Applexus to streamline its SAP ECC custom code landscape ahead of an S/4HANA transformation. The client faced challenges with code complexity, limited visibility, and outdated developments. Using CeleRITE, Applexus identified what to retain, remediate, or retire, while uncovering technical debt and mapping key dependencies. The engagement delivered actionable insights that accelerated planning, reduced manual analysis, and set a strong foundation for a cleaner, more efficient move to S/4HANA.

Success Stories Components

Title

Client Overview

Description

A global consumer electronics company preparing for an S/4HANA transformation engaged Applexus to gain early visibility into its SAP ECC custom code landscape. The client’s system had grown over time to include a significant volume of custom developments, making it essential to understand what could be retained, remediated, or retired in the new environment.

Business Challenges

Lack of consolidated information on the total volume and usage of RICEFW objects
Presence of over 175,000 custom objects, including large numbers of cloned or redundant developments
No clear visibility into which custom objects were in use and which were obsolete
Difficulty in estimating remediation effort for custom code during S/4HANA transition
Limited documentation on interdependencies between custom developments and standard SAP functionality
Need for detailed insights to support planning, testing, and resource allocation for the S/4 transformation project

Applexus Engagement

Applexus was brought in to assess the client’s SAP ECC system with a specific focus on their custom code landscape, which had grown significantly over time. We did this with the help of CeleRITE, our AI-powered S/4HANA assessment and migration platform.

A core feature of CeleRITE is the Code Transformation Studio, purpose-built to analyze custom objects in depth. It identifies unused code, redundant logic, and potential compatibility issues with S/4HANA. Beyond assessment, it delivers insights on code usage and quality, identifies code segments for targeted remediation, and uses AI to generate clear, detailed documentation.

What We Did

Running CeleRITE across the system to analyze all RICEFW and custom objects
Conducted a workshop with their existing S/4HANA transformation partner
Subgrouping executable programs based on functional areas
Identifying high-volume, low-usage objects suitable for archiving
Mapping dependencies and pinpointing entry and exit points to aid test planning

Solution Highlights

Analyzed over 175,000 custom objects, including 100,000+ add-ons
Evaluated 10 million+ lines of ABAP code for complexity, usage, and quality
Conducted usage analysis for 11,000+ RICEFW objects, including dependencies
Grouped custom programs functionally to assist in fit-gap and process design
Identified 500+ cloned objects flagged for archiving or consolidation
Mapped interdependencies between custom objects and core SAP modules
Identified entry and exit points for RICEF objects to support end-to-end testing and traceability

Key Outcomes

Description

Detailed RICEFW Inventory: Delivered a complete inventory of all RICEFW objects, annotated with usage metrics and dependency mappings, enabling stakeholders to prioritize remediation and reduce analysis time during design.
Custom Object Rationalization: Helped identify actively used vs. obsolete custom developments, supporting early archiving decisions and helping reduce technical debt ahead of migration.
Code Quality and Readiness Insights: Highlighted key quality issues in legacy code including performance bottlenecks, redundant logic, and non-compliant structures that could impact the stability or compatibility of the future S/4HANA environment.
Testing Acceleration: By identifying entry and exit points for custom objects, the assessment enabled faster creation of test scripts and ensured more complete coverage during integration and user acceptance testing phases.
Dependency Mapping: Provided transparency into complex interdependencies across programs, function modules, and enhancements allowing smoother scoping for reengineering and reducing the risk of downstream disruption.
Transformation Planning Enablement: Assisted the project team with structured, data-backed documentation to accelerate pre-conversion planning, reduce uncertainties, and improve coordination across functional & technical workstreams.
