Custom Code Assessment for SAP S/4HANA Migration

  1. Preparation:

    • Inventory: Identify and catalogue all custom code in your current SAP system.

    • Training: Ensure your project team is trained on custom code migration topics.

  2. Custom Code Analysis:

    • SAP S/4HANA Checks: Use SAP’s tools to analyze custom code and identify necessary adaptations. This includes running SAP S/4HANA custom code checks to evaluate custom objects.

    • Central Check System: Utilize systems like SAP S/4HANA, SAP NetWeaver Application Server for ABAP, or SAP BTP ABAP environment as the central check system.

  3. Adaptation:

    • Simplification Database: Import the simplification database to understand the changes in SAP S/4HANA and adapt your custom code accordingly.

    • SPDD and SPAU Transactions: Use these transactions to adjust dictionary objects and repository objects.

    • ABAP Development Tools: Adapt custom code using ABAP development tools for Eclipse.

  4. Post-Migration:

    • Testing: Thoroughly test the adapted custom code to ensure it functions correctly in the new SAP S/4HANA environment.

    • Optimization: Continuously monitor and optimize custom code to maintain performance and compliance with SAP S/4HANA standards.

Tools and Resources

  • Custom Code Migration App: This app helps analyse custom code for migration, providing graphical representations and filtering options based on various categories.

  • SAP Fiori App: Recommended for custom code analysis, offering a user-friendly interface and detailed insights.

Custom code assessment plays a crucial role in improving efficiency during the migration to SAP S/4HANA.

Key Benefits of Custom Code Assessment

  1. Identifying Necessary Adaptations:

    • Custom code assessment helps identify which parts of your existing custom code need to be adapted for SAP S/4HANA. This ensures that only relevant changes are made, reducing unnecessary work.

  2. Automated Tools:

    • SAP provides automated tools, such as the Custom Code Migration App and SAP Fiori App, to analyze custom code. These tools streamline the assessment process, making it faster and more accurate.

  3. Simplification Database:

    • The simplification database provides detailed information on changes in SAP S/4HANA, helping you understand what needs to be adapted in your custom code. This reduces the time spent on manual analysis.

  4. Central Check System:

    • Utilizing a central check system, such as SAP S/4HANA or SAP BTP ABAP environment, allows for efficient analysis and adaptation of custom code. This centralization simplifies the process and ensures consistency.

  5. Reduced Manual Effort:

    • Automated checks and detailed analysis tools reduce the manual effort required for custom code migration. This allows your team to focus on higher-value tasks, improving overall efficiency.

  6. Compliance and Performance:

    • Ensuring that custom code is compliant with SAP S/4HANA standards and best practices enhances system performance and reliability. This reduces the risk of issues post-migration, saving time and resources.

The custom code assessment process ensures compliance with SAP S/4HANA standards and best practices through several key steps:EHP upgrades are designed to perform seamlessly on both SAP HANA in-memory platforms and traditional databases, providing flexibility for your IT infrastructure.

Key Steps in Custom Code Assessment

  1. Automated Checks:

    • SAP S/4HANA Readiness Check: This tool automatically scans your custom code to identify potential issues and necessary adaptations. It highlights areas that need to be updated to comply with SAP S/4HANA standards.

    • Code Inspector and ABAP Test Cockpit (ATC): These tools perform static code checks to ensure that custom code adheres to SAP’s best practices and guidelines.

  2. Simplification Database:

    • The simplification database provides detailed information on changes in SAP S/4HANA. It helps identify obsolete or changed functionalities, guiding the necessary adaptations in custom code.

  3. Central Check System:

    • Utilizing a central check system, such as SAP S/4HANA or SAP BTP ABAP environment, allows for efficient analysis and adaptation of custom code. This centralization ensures consistency and compliance with SAP standards.

  4. ABAP Development Tools:

    • ABAP development tools for Eclipse facilitate the adaptation of custom code. These tools provide a modern development environment with features that help ensure compliance with SAP S/4HANA standards.

  5. SPDD and SPAU Transactions:

    • These transactions are used to adjust dictionary objects and repository objects during the upgrade process. They help ensure that custom code is aligned with the new system’s requirements.

These steps and tools collectively ensure that custom code is compliant with SAP S/4HANA standards and best practices, reducing the risk of issues post-migration and enhancing overall system performance.

Custom code assessment significantly reduces the effort required for SAP S/4HANA migration by streamlining the process and ensuring compliance with SAP standards. 

By leveraging these tools and processes, custom code assessment significantly reduces the time and effort required for migration, ensuring a smoother transition to SAP S/4HANA. This leads to improved operational efficiency and allows your business to quickly realize the benefits of the new system.
