With the advent of cloud technology and the migration path to SAP S/4HANA, organizations are seeking increasingly streamlined. Furthermore, cost-effective methods to optimize their environments including SAP.

In this blog we discuss in details code remediation for custom code migration, clean core strategy and ABAP readiness to ensure you maximize the benefits of SAP RISE with confidence.

Understanding SAP RISE Custom Development

Overview of SAP RISE
SAP RISE is SAP’s business transformation solution in the cloud. It provides a cloud infrastructure and market leading fluids technology in one.

It brings the intelligent enterprise to the customer via SAP Business Process Intelligence and technology services. By catalyzing businesses to implement a swift turn toward digital transformation.

Why Custom Development?

Custom Solutions: No 2 businesses are exactly the same. With RISE, customers can tailor their ERP to trim operations.

Flexible Problem Solving: You can respond to a specific challenge, that may not be accommodated by standard SAP functionality with the help of Custom Code.

Improved Optimization: We help businesses to use SAP features in the best approach for their own needs via custom development.

Custom Code Migration
When transitioning to SAP S/4HANA we must also when migrating custom code. Custom code migration means moving applications, which have been developed in-house, from older systems to SAP S/4HANA without destabilizing or slowing down the system.

Benefits of Custom Code Migration:

Minimized Downtime: With an organized guideline for migration, companies can minimize the downtime in transitions and operate more seamlessly.

Better System Performance: Upgrading to SAP S/4HANA makes your system faster as real-time data processing. It is feasible and overall system performance is better.

Cleaner Maintenance: Not to forget that since we moved the code base it is also cleaner thus maintaining stuff will be easier.

Maintaining a Clean Core

What is a Clean Core?
A clean core is about trying to have as little custom code in your SAP system as possible. By avoiding unneeded customizations and sticking as closely to the standard SAP solutions, companies keep their SAP system flexible. As well as implemented in a scalable fashion, and also easier to maintain.

Why Keep a Clean Core?

Smoother Upgrades: Maintain a cleaner core for an easier upgrade process and avoid compatibility issues when updating your version.

Maintain Lower Maintenance Costs: Organizations can save money and effort by keeping the system less complex which would have ensued if they avoided over-customization.

Strategies to Get a Clean Core:

Leverage Standard SAP: Don’t re-invent the wheel if you don’t have to.

Ongoing Review and Enhancements: Avoid complexity by periodically reviewing your custom code, deleting what you don’t need, and optimizing.

ABAP Readiness
ABAP (Advanced Business Application Programming) the language is implemented in these applications, but no knowledge of ABAP syntax is required to work with the app.

With the move to SAP S/4HANA and the cloud, it is important for companies to make sure that their custom ABAP code remains compatible with new landscapes.

Steps for ABAP Readiness:

Code Readiness: Read existing ABAP code and check its suitability for SAP S4 HANA and cloud. Find redundant features and applications where off-the-shelf solutions can be used instead of custom-built systems.

Code Remediation: Fix problem areas, including outdated functions and code optimization to maintain functionality within the new environment.

Continuous Testing and Validation: Test your custom code on a regular basis to ensure that it is compliant with the needs of SAP S/4HANA so that it remains consistent with SAP’s most up-to-date features and recommendations.

ABAP readiness directly leads to the custom code be ready for usage in SAP’s cloud world and therefore there will be lesser friction and integration enablement.
