The Critical Role of Testing in Seamless SAP S/4HANA Migration

Listen on the go!

Why Organizations Should Migrate to SAP S/4 HANA by December 2027?

Organizations must migrate to SAP S/4HANA by December 2027. Using technologies beyond their End of Life (EOL) can lead to operational disruptions, increased maintenance costs, costly support services, security vulnerabilities, and compliance failures, ultimately resulting in higher expenses and diminished customer experiences.

This short timeframe requires immediate planning.

End of Support Deadlines By the end of 2027, SAP will end support for ERP 6 EHP (6-8), and for ERP 6 EHP (0-5) by 2025. Customers must migrate to SAP HANA databases to remain supported.
Impact of Database Vendor EOL Dates Database vendors like Microsoft and Oracle may have different end-of-life dates for SAP-supported databases. Customers need to track these dates to avoid disruptions in their SAP environments.
Migration and Support Continuity SAP support ends on December 31, 2027. To avoid service interruption, plan your SAP ERP database migration to SAP HANA to ensure continued support until that date.

According to Gartner, only 33% of SAP users relying on its legacy ECC ERP system have purchased or subscribed to licenses to transition to S/4HANA.

As the migration deadline nears, the analyst research outlines that one-third of ECC users have not acquired S/4HANA, and only one-fifth use the latest SAP ERP version in any component.

Why Testing is Critical

Transitioning to S/4HANA requires transferring vital business data to a new database structure. This migration presents challenges due to SAP data’s crucial role in financials, HR, and supply chain. Risks include data inconsistencies, issues with bespoke functionalities supporting business processes, and the possibility of system downtimes affecting business operations.

DSAG, an association representing SAP users in Germany, Austria, and Switzerland, revealed findings from a member survey, indicating a growing focus on Security and AI. The survey highlighted that 88% of respondents rated security as medium or high relevance, underlining its importance.

This underscores the critical role of comprehensive testing in ensuring successful SAP HANA migration. However, devising a seamless testing strategy without any hiccups remains a challenge.

What are the testing challenges of SAP migration?

The following challenges arise during the S/4HANA readiness assessment testing:

High Cost Manual testing often exceeds 30% of a typical SAP project budget.
Time-Consuming Manual testing delays S/4HANA implementation due to its lengthy process.
Lack of Accuracy Prone to human error, manual testing can compromise accuracy.
Management Challenges Managing and tracking test progress is difficult with manual methods.
Limited Collaboration Manual testing hampers collaboration among teams and stakeholders.
Complexity Testing the multiple functionalities and modules of S/4HANA is challenging.
Test Automation Gaps Many companies lack the tools and resources for effective test automation.
Maintenance Issues The complexity of S/4HANA makes maintaining test cases difficult.
Identifying Test Cases It’s challenging to determine which test cases to run in S/4HANA.
Measuring Impact Manual testing struggles to measure the impact of system changes.

Top 3 Testing Recommendations for SAP S/4HANA Migration:

Given the extensive architectural and functional modifications, conducting comprehensive testing on new and existing features is crucial when transitioning to SAP S/4HANA. This is imperative to guarantee seamless continuity of business operations, systems, and processes throughout and post-migration.

Functional testing ensures that all modules, from procurement to financial reconciliation, work correctly in the new environment, verifying transaction execution, business process continuity, and interface integrity. Due to the migration’s complexity, test automation is essential for enhancing efficiency, repeatability, and speed, surpassing the limitations of manual testing. Performance testing is crucial to ensure the system meets performance benchmarks and maintains efficiency and stability even under peak loads with the new functionalities and HANA database. Accurate and functional BI reports are vital for decision-making throughout this process.
