What our customers are saying

"Companies already deeply entrenched with SAP should seriously think about smartShift, which is the best solution for custom code remediation. When you’re doing your S/4HANA transformation, I’d advise you to include smartShift in your approach. Inject smartShift early, when the train is still moving— otherwise, you’ll have to stop the train like we did. Or you might get into a train wreck.”

Charles Ahn, Director of SAP Technology Enablement and Integration Kimberly-Clark

"You hear about S/4HANA upgrades going south. That did not happen to us. The number of defects we had after go-live was so tiny it was just incredible."

Keith Smith, SAP Solutions Director, CONA

Upgrade Before the Deadline Hits

If you’re facing an upcoming S/4HANA version upgrade, the clock is ticking — and the risks are real. Whether you’re under pressure to meet end-of-maintenance deadlines or dealing with unstable custom code, smartShift helps you take control with automation, precision, and speed.

What is SAP custom code transformation in an SAP S/4HANA migration?

SAP custom code transformation during an S/4HANA migration is the process of adapting, remediating, and optimizing a company's legacy ABAP code to ensure it functions correctly, securely, and efficiently in the new SAP S/4HANA environment.

Because S/4HANA is a complete rewrite designed specifically for the HANA in-memory database, migrating from legacy SAP ECC introduces widespread incompatibilities related to data models, underlying database technology, and ABAP language syntax. If these incompatibilities are not addressed, the legacy custom code can cause severe functional errors, system instability, and production outages.

A comprehensive custom code transformation process goes beyond simple "find and replace" syntax fixes and encompasses several critical steps:

Compatibility Remediation: Resolving mandatory syntax errors and adapting legacy data structures to ensure the code interacts properly with the S/4HANA architecture and the HANA database.
Performance Optimization: Applying SAP's "Golden Rules" for SQL and tuning the code to fully leverage the speed of the HANA in-memory database.
Security and Stability: Hardening the code by detecting and correcting vulnerabilities (such as missing authorization checks or code injection risks) and removing potential runtime errors.
Code Decommissioning: Identifying and safely deactivating obsolete or completely unused custom code, which drastically reduces the organization's technical debt and shrinks the scope of future maintenance.
Clean Core Modernization: Refactoring code to implement current SAP ABAP guidelines and best practices, preparing the system for cloud-compliance (ABAP Cloud) and modern extensibility models.

Traditionally, organizations relied on a massive deployment of developers to spend months or years manually identifying and rewriting these code issues. However, the modern standard is to use Intelligent Automation for the transformation. In an automated approach, tools like smartShift extract the custom codebase, parse it into a language-independent meta-model, and automatically apply thousands of AI-driven rules to rewrite the logic. The modernized, S/4HANA-compliant code is then automatically uploaded back into the target system—allowing millions of lines of code to be transformed in weeks with a 99.99% accuracy rate.

How does ECC end-of-support impact custom enhancements and modifications?

The impending end of mainstream support for SAP ECC in 2027 forces organizations to migrate to S/4HANA, which profoundly impacts legacy custom enhancements and modifications. Because S/4HANA is not just an evolution of ECC but a complete rewrite designed specifically for the HANA in-memory database, legacy custom code cannot simply be moved to the new environment as-is.

The transition impacts custom enhancements and modifications in the following ways:

Widespread Incompatibilities: Foundational changes to the software, underlying database technology, table structures, and ABAP language syntax introduce hundreds of thousands of custom code incompatibilities. These incompatibilities require extensive adjustments to millions of lines of legacy code to ensure it continues to function properly.
Reconciling Modifications (SPDD/SPAU): Any modifications previously made to standard SAP objects must be carefully evaluated and reconciled during the system upgrade. This process uses SAP transactions like SPDD (for data dictionary objects such as tables and structures) and SPAU (for standard code objects) to determine which custom changes should be retained in the new S/4HANA environment and which can be reverted to the SAP standard. If not performed correctly, these unresolved modifications can cause critical issues for the upgrade.
Modernizing Custom Fields: Legacy enhancements known as "Classical Custom Fields" (e.g., legacy table appends) do not follow modern SAP Clean Core principles. To function properly with modern S/4HANA innovations—including native SAP Fiori apps, standard CDS views, and APIs—these must be transformed and migrated to new Key User custom field extensions.

Ultimately, the ECC end-of-support requires organizations to comprehensively analyze, remediate, and optimize their custom ABAP codebase to guarantee S/4HANA compatibility, maintain system stability, and align with future-ready Clean Core architecture.

How do you identify which custom code needs remediation before migration?

Identifying which custom code requires remediation before migration is accomplished through a comprehensive, automated evaluation of the entire SAP custom code repository using the smartShift Code Analysis solution and the Intelligent Automation Platform. This process goes beyond basic scanning by combining multiple analytical methods to precisely define the scope of transformation:

Data Extraction and Usage Analysis: The process begins by extracting custom developments, object metadata, and historical production usage data utilizing sources like ST03N, UPL, SCMON, or SUSG. By evaluating this statistical data—ideally covering 13 months to capture year-end activities—the analysis separates actively used objects from unused ones. This crucial step allows organizations to safely decommission obsolete code, thereby drastically reducing technical debt and the overall scope of code that actually needs remediation.
Deep Code Parsing and Meta-Modeling: The platform's Analysis Engine parses all custom code and re-engineers it into a language-independent meta-model. This allows the platform to comprehensively evaluate the logical constructs, data declarations, data flows, and complex inter-object dependencies across the entire system, rather than relying on simple pattern matching.
Rule-Based Technical Evaluation: The platform evaluates every object in the meta-model against a library of over 240 AI-driven rulesets. This identifies mandatory changes for S/4HANA, HANA database, and Unicode compatibility, while also flagging code for performance optimization, security vulnerabilities, and ABAP modernization.
Integration with SAP Standard Tools: The automated analysis integrates results from SAP's own tools, specifically the ABAP Test Cockpit (ATC) S/4HANA Readiness variant report and the Simplification List. The Analysis Engine combines these ATC results with its own deep-dive analysis to evaluate specific functional impacts, data model changes, and obsolete SAP components that require customer attention.
Landscape Comparison and Reconciliation: To ensure the correct code is transformed, the analysis compares custom code across different system environments, such as Development, QA, and Production. This identifies version inconsistencies and source code conflicts, ensuring that obsolete objects in the production environment do not overwrite active development.
Interface and Dependency Mapping: The analysis maps out all system interfaces, file access points, and external database calls, uncovering latent dependencies within the custom code that might break or require architectural realignment during the transition.

By synthesizing these insights, the analysis generates actionable reports, risk scoring, and a precise, fixed-bid project plan that eliminates the guesswork from determining the remediation scope.
