SAP Code Consolidation

SAP Code Consolidation is the complex process of merging custom code, data dictionary (DDIC) objects, and functionalities from multiple separate SAP instances (source systems) into a single, unified target system. This initiative is typically driven by structural changes to a business, such as Mergers and Acquisitions (M&A) activity, divestitures, reorganizations, or as a strategy to reduce landscape complexity and IT overhead during a move to SAP S/4HANA.

The Challenge of Traditional Consolidation

Historically, consolidating SAP systems manually has been prohibitively complex and risky. Key challenges include:

• Source Code Conflicts: Different systems often have custom objects with the same names but entirely different logic, or identical logic saved under different names (clones).

• Complex Enhancements: Merging customizations like user-exits, form routines, and BADIs across multiple systems is highly intricate.

• Hardcoded Values: Legacy systems are frequently plagued by hardcoded business entities, file paths, and literal values that will break when moved to a new unified environment.

• High Risk and Testing Burden: Relying on manual cross-system comparison and "trial and error" deployment models results in a massive testing scope, run-time stability issues, and the severe risk of losing critical business processes during the move.

The smartShift Automated Consolidation Approach

smartShift addresses these challenges using Intelligent Automation, replacing manual guesswork with data-driven planning and automated execution. The approach is broken down into two main phases:

1. Consolidation Analysis. Before any code is moved, smartShift performs an automated cross-system analysis comparing the source code and DDIC objects of the systems in scope. This analysis exposes differences and similarities to inform the consolidation strategy by discovering:

• Common code and clones across the source systems.

• Conflicts within the source code and meta-data of custom objects.

• Dependencies on 3rd-party applications, add-ons, and embedded custom frameworks.

• Locations of hardcoded technical and business entities.

2. Automated Consolidation & Harmonization. Once the data-driven scope is defined, smartShift utilizes its Application Transformation Engine to automatically extract, merge, and integrate the custom objects into the target system. This includes:

• Conflict Resolution: Automatically performing dependency analysis, renaming, and refactoring conflicting objects to safely move them into a customer namespace.

• Hardcoded Literal Replacement: Finding and replacing hardcoded values to ensure the code functions correctly in the new combined process mapping.

• User-Exit Frameworks: Automatically harmonizing and transforming existing modifications and user-exits to fit the new unified system.

• Target System Compatibility: If the consolidation is occurring alongside a migration, the consolidated code is simultaneously optimized for HANA and S/4HANA compatibility, security, and performance.

By automating the analysis and merging of custom repositories, smartShift ensures application integrity, functional harmonization, and targeted testing, allowing enterprises to complete massive system consolidations in a fraction of the time with minimal risk.

SAP consolidation is typically required after a merger or acquisition (M&A) when structural changes to the business necessitate modifying the structure of the organization's IT systems.

When companies merge or acquire other businesses, they often end up operating multiple separate SAP instances, which can hinder the overall advantages of the M&A. Consolidation becomes necessary to reduce this landscape complexity by extracting, merging, and integrating custom code, enhancements, and data dictionary (DDIC) objects from the various source systems into a single, unified target system.

Specifically, this consolidation process is required to ensure the newly unified system functions properly by:

• Resolving technical conflicts and commonalities between the different codebases.

• Understanding and harmonizing complex object dependencies across the merged systems.

• Identifying and replacing hard-coded literal values that would otherwise break or cause errors when moved into a new, consolidated environment.

The timeframe for a typical SAP consolidation using smartShift's automated approach depends on the number of systems involved, but for a standard landscape of up to three systems, the process is generally divided into two main phases:

• Consolidation Analysis (8 weeks): The initial assessment phase typically takes 8 weeks for a maximum of 3 systems, with custom timelines developed for larger landscapes. This data-driven planning phase is broken down into a 4-week "Identify" stage to extract and analyze code, a 2-week "Scope" stage for collaborative review workshops, and a 2-week "Plan" stage to finalize the delivery roadmap.

• System Consolidation Execution (12 to 15 weeks): The actual automated extraction, merging, conflict resolution, and harmonization of the custom code into the single target system takes approximately 12 to 15 weeks for up to 3 systems.

By leveraging Intelligent Automation, this approach drastically reduces the project timeline compared to traditional manual consolidation methods, which are often plagued by long testing cycles and risky "trial and error" deployment models.

Automation fundamentally transforms SAP custom code consolidation from a risky, error-prone manual exercise into a predictable, highly accelerated, and data-driven process. Traditional manual approaches rely on complex cross-system comparisons and a "trial and error" deployment model, which leads to large testing scopes, runtime stability issues, and the risk of losing critical applications.

By leveraging Intelligent Automation, organizations improve the consolidation process in several critical ways:

• Comprehensive Cross-System Analysis: Rather than relying on human developers to manually compare systems, automation brings all repositories into one place and instantly exposes the differences and similarities. It identifies common code (clones), deep object dependencies, and specific technical conflicts across the different source systems to enable highly accurate, data-driven planning.

• Automated Conflict Resolution: When merging multiple SAP instances, code conflicts are inevitable. Automation automatically performs dependency analysis and resolves conflicts by renaming and refactoring custom objects so they can be safely integrated into the new, unified target system.

• Code Harmonization and Optimization: Automation systematically identifies and replaces hardcoded literal values (such as file paths or business entities) that would break when moved to a new environment. Furthermore, it merges complex user-exits and simultaneously transforms the legacy code to ensure it is fully compatible, secure, and performant for the new HANA or S/4HANA environment.

• Massive Reductions in Risk and Manual Labor: Because the automation guarantees application integrity and creates accurate change logs, it eliminates the need for massive manual code rewrites and allows organizations to perform highly targeted testing.

Real-World Impact: The value of this automated approach is evident in enterprise-scale projects. For example, when OMV consolidated two highly customized ECC systems across 10 countries into a single S/4HANA system, manual remediation would have required a massive team of developers trawling through code. Instead, smartShift's automation analyzed over 48,000 custom objects and automatically renamed, refactored, and remediated over 10,000 of them. This automated consolidation successfully resolved conflicts and achieved S/4HANA compatibility while reducing the internal workload on OMV's team by 67%.

No, business operations will not be disrupted during the transformation process. smartShift’s solutions are specifically engineered to eliminate the system downtime, project delays, and restrictive code freezes that traditionally stall business velocity during major SAP initiatives.

Here is how smartShift ensures your operations continue to run smoothly:

• Dual Maintenance: Traditional SAP upgrades typically require a "code freeze," meaning all ongoing development and system enhancements must be halted. With smartShift’s Dual Maintenance solution, your teams can continue making business-as-usual changes, bug fixes, and innovations in your current production environment. smartShift automatically detects, transforms, and synchronizes those updates into your new project landscape (such as S/4HANA) in real time, ensuring both systems stay aligned without manual rework or code conflicts.

• Non-Disruptive Code Transformation: The actual process of analyzing and remediating your custom code happens outside of your live SAP system. smartShift extracts the code, transforms it using its Intelligent Automation platform, and only uploads the modernized code to a designated transport in the target system once it is completely optimized. No changes are applied to your active system until you are thoroughly prepared to proceed.

• Safe Security Implementations: When applying security remediations, smartShift uses a unique framework that allows changes to be tested in an "audit (soft-error) mode". This enables your team to safely observe how security changes behave in the background without actually blocking legitimate users or critical business processes. Once the security model is perfectly tuned based on these observations, strict rules can be enforced without any unexpected business disruption.

Real-World Success: Large global enterprises consistently rely on this zero-disruption approach. For example, during a massive multi-year S/4HANA transformation, Procter & Gamble was able to run hundreds of parallel innovation projects without stopping a single one, noting that business operations continued "as if the transition to S/4HANA was not happening". Similarly, CONA Services (Coca-Cola) successfully implemented 1,500 system changes every month throughout their two-year S/4HANA migration without ever needing to slow down operational requests from their bottlers.

Before executing an SAP system consolidation, rigorous data-driven planning and technical preparation are required to mitigate risk and ensure a smooth merge. Rather than relying on guesswork, smartShift prepares for the transition through an initial 8-week Consolidation Assessment phase.

The key preparation steps include:

• Technical Setup and Data Extraction: Preparation begins by installing the smartShift Code Extractor on all source systems in scope. Customers also need to provide system access and supply historical SAP statistical usage data (via ST03N, UPL, or SCMON) to help identify actively used versus obsolete code across the environments.

• Automated Consolidation Analysis: Before any code is moved, smartShift performs a comprehensive cross-system analysis comparing the custom ABAP and Data Dictionary (DDIC) objects across all the merging landscapes. This automated assessment quantifies the differences and similarities, exposing common code (clones), hardcoded literals, embedded custom frameworks, third-party dependencies, and exact technical naming conflicts.

• Collaborative Scoping Workshops: smartShift experts and customer stakeholders from all workstreams participate in joint review workshops to evaluate the summary reports, gauge the impact on existing priorities, and review options for code harmonization. This step ensures the precise scope and conflict resolution strategy are agreed upon before execution.

• Detailed Delivery Planning: Finally, the analysis findings and workshop decisions are integrated to create a concrete, actionable project plan. This yields a detailed work breakdown structure, landscape design, transport process document, and a fixed-price, SLA-backed delivery roadmap.

By conducting this extensive data-driven scoping and analysis upfront, organizations replace traditional trial-and-error deployments with a definitive blueprint, allowing the actual automated consolidation to proceed rapidly and safely.

The costs involved in an SAP consolidation project with smartShift are determined using a fixed-price, fixed-timeline model, which eliminates the financial uncertainty and subjective hourly billing typically associated with manual system integrators.

Because every SAP landscape is unique, the exact cost is calculated based on the size and complexity of your specific systems. The costs are generally broken down into three main components:

• Consolidation Analysis (Assessment): The initial 8-week assessment phase, which maps out the exact technical scope, conflicts, and dependencies across the systems being merged, is delivered at a low fixed cost.

• System Consolidation and Code Transformation: The cost for the actual automated extraction, conflict resolution, and code merging is based on the maximum number of custom objects in your repository that require transformation. At the end of the analysis phase, smartShift provides a firm, SLA-backed proposal locking in this cost.

• Dual Maintenance: If your consolidation requires keeping the legacy systems running and synchronized while the new target system is being built, dual maintenance fees are applied. This cost is determined by the length of time dual maintenance is required and the maximum number of objects updated per quarter.
