Businesses need to ensure that their mission-critical custom applications work well in the new environment when moving from traditional SAP ECC to S/4HANA. It is for this reason that many ABAP customizations are remedied. What exactly does this entail? Here’s what you need to know.

What is ABAP Code Remediation?

ABAP code remediation makes sure that teams can continue to access their custom applications on new SAP systems. This ensures that SAP S/4HANA applications are compatible with SAP ECC.

There are two options: ABAP modernization, in which developers implement the essential functions of ABAP and incorporate them into the SAP S/4HANA environment, or ABAP code optimization.

The process ensures business processes are not interrupted due to changes in inputs and outputs after system conversion. The applications present in the old system work in the updated one.

Why do we need ABAP code remediation in SAP?

SAP HANA is the underlying system for SAP Business Suite and SAP NetWeaver Business Warehouse. OLTP (transnational) and OLAP (analytical) processing are also fully optimized in the system.

However, SAP HANA’s In-Memory columnar storage requires additional recommendations. It is also necessary to revisit and adapt some database aspects specific to ABAP coding. Therefore, ABAP SAP Custom Code is important.

Your development team must first identify the changes that need to be made to your custom code. They must also determine which SQL operations need to be optimized before converting to SAP HANA.

Tools for ABAP custom code analysis

Performance optimization of custom ABAP programs relies heavily on the following tools.

SQL monitor

The SQL Monitor is an evaluation system within the ABAP-based SAP system. In addition to identifying performance hotspots within the system, the tool also identifies potential areas for optimization. Using the SQL monitor, you can monitor all SQL statements and operations, especially when running ABAP applications.

ABAP test cockpit

The ABAP Test Cockpit integrates seamlessly with the ABAP Workbench. During development, it executes and displays static usability tests, module tests, package checks, security checks, statistical performance tests, and extended programs.

SQL performance tuning worklist

The SQL Performance Tuning Worklist is a tool to identify candidates for performance tuning. Potential candidates are identified by evaluating runtime data from SQL Monitor. Using SQL Monitor data, you can also rank findings based on performance.

SAP Fiori App

The SAP Fiori App is useful for analyzing custom ABAP code for SAP and S/4HANA to assess readiness for migration. Assessing the adaptability of ABAP custom code by performing advanced analyses is paramount. Additionally, the app improves the UI to improve the user experience for consumers.

Other options

It is a viable option to remediate the ABAP code. Custom apps can, however, be migrated to the updated SAP environment through other methods.

Rehost

In Rehost, you can move the application from the SAP system and host it in a cloud-native application. Customizations, including Z-Tcode and ABAP reports, can be separated from SAP core and hosted outside SAP ERP. The process is also called side-by-side extension by SAP. When doing this, ensure that you know how to use text symbols in the SAP ABAP editor.

Rebuild

Rebuild is an ideal option for ABAP customizations that are old but still useful. This is a cheaper option to consider during the S/4HANA migration. The process lowers maintenance costs and also requires no code and no tools.

Refactor

Refactoring is the process whereby the program is customized to run on modern devices like mobile phones, tablets, or remote locations. During reprogramming, ABAP programs, including their text, were enhanced to widen their applications.

Reimagine

This is reimagining how your business processes operate by rethinking the application’s processes and functions during a S/4HANA upgrade. The process is also critical in adapting to the different dynamics of the business environment after integrating a simplified database.

Replatform

You have the option of changing the application platform to a more modern one while maintaining the original application model. In this process, the original application logic including the primary key is maintained; only the platform changes.

The Right Recommendation for Customers

Before deciding on the best customer recommendation, the ABAP lead and the project manager must decide on several issues. Here is what they need to assess
What changes are essential so that you can incorporate them into the code

  1. The amount of effort that is required for custom ABAP code remediation
  2. The process of tracking changes
  3. How to assess the performance of the code after it has been adapted in the SAP HANA database.
  4. Conducting code inspection before SAP note implementation, here you can work with a code inspector for a thorough inspection

Following quotations of essential changes to be incorporated, implementation is the next step. It is also criticalto identify the right technology for ABAP custom code migration and ABAP code remediation. SmartShift Technologies offers customers automated processes to de-risk their SAP transformations. In addition, It is also imperative to be able to check the namespaces/packages that are useful for custom code remediation.

Businesses can also work with companies like Secure Code Warrior to train their ABAP developers and ensure they get continuous support. “Migrating to SAP S/4HANA is almost always a long-term project” Gekkobrain emphasizes the importance of getting all the support needed.

Monitoring the effectiveness of code remediation during and after the migration is crucial to preventing any inefficiencies or delays caused by potential issues. Static checks can also be conducted by developers to identify errors.
