Ensuring 100% Reporting Continuity During S/4HANA Transformation
Overview
ERP transformations are often judged by system go-live. In reality, success depends on whether business users continue to trust their data. A global semiconductor enterprise faced this exact challenge while moving from SAP ECC to S/4HANA. Applexus ensured that reporting remained stable, consistent, and trusted despite major changes in the underlying data landscape.
The Challenge
The analytics ecosystem depended on 369 SAP tables across 10 business functions, including finance, supply chain, and operations. These data structures powered reporting through Snowflake and Power BI.
During the transition to S/4HANA, table structures, field definitions, and data models were expected to change. This created a high risk of broken reports, inconsistent outputs, and loss of business confidence.
Without a structured approach, the organization faced the possibility of reporting failures, incorrect decision-making, and costly rework after go-live.
The Approach
Applexus approached the initiative as a structured analytics transformation rather than a technical migration.
The team conducted a full landscape assessment, analyzing table dependencies, data flows into Snowflake, and reporting logic in Power BI. This enabled clear classification of what could be retained, redesigned, or re-engineered.
Using accelerators, Applexus mapped dependencies across all impacted tables and business domains, ensuring no critical relationships were missed.
A structured retrofit strategy aligned ECC data structures with S/4HANA equivalents while preserving business meaning and minimizing rework.
A multi-level validation framework ensured consistency across data, logic, and reporting outputs, validating not just system performance but business outcomes.
