Asia’s Leading Cement Manufacturer Future-Proofs Its IT Landscape with Coforge’s SAP S/4HANA Brownfield Migration

Scope

The engagement covered end-to-end SAP S/4HANA Brownfield Migration, including:

• SAP Modules: Sales & Distribution (SD), Finance & Controlling (FICO), Materials Management (MM), Human Capital Management (HCM), Production Planning (PP), Plant Maintenance (PM), Quality Management (QM), Project Systems (PS), SAP BASIS & GRC, Fiori and PO to Cloud Platform Integration (CPI).
• Greenfield Implementation: Group reporting and SAC Implementation.
• Third-Party Integrations: SFDC, Oracle Transportation Management (OTM), Ariba, SuccessFactors, DMS, and multiple banking systems
• User Base: 4,500+ users across seven business operations

Challenges

• Extensive Code Complexity: Over 11,000 custom ABAP objects required remediation to align with S/4HANA standards.
• High Integration Density: More than 350 integration objects with 35+ non-SAP systems required re-mapping due to obsolete tables and T-Codes.
• Business Partner Conversion: Transitioning from traditional master data models to Business Partner framework caused integration challenges for external applications.
• Technology Upgrades: Conversion of legacy FIORI applications and migration of BI data sources to CDS views posed technical challenges.
• Settlement Management Migration: Rebate management migration to S/4HANA Settlement Management required extensive testing and reconfiguration.
• Custom FSCM Integrations: Highly customized Financial Supply Chain Management (FSCM) processes led to integration complexities, as standard functionalities were not adopted.
• Extensive Testing & Training Needs: Multiple dependencies, sub-process complexities, and new functionalities necessitated detailed user training and large-scale testing cycles.

Solution

Coforge adopted a structured Brownfield migration approach, balancing system conversion efficiency with risk mitigation:

• Comprehensive System Assessment:
• Performed detailed code and data remediation planning for 11,000+ custom ABAP objects.
• Designed integration mapping blueprints to ensure clean connectivity with 35+ non-SAP applications.
• Clean Core Implementation:
• Established a “clean core” integration architecture through SAP Cloud Platform Integration (CPI) for over 350 objects, ensuring maintainability and scalability.
• Rationalized and consolidated multiple FIORI applications into a unified, embedded FIORI version for improved usability and governance.
• Targeted Functional Enhancements:
• Migrated rebate management to S/4HANA Settlement Management with thorough configuration and regression testing.
• Initiated greenfield implementation of Group reporting and SAP Analytics Cloud as part of the S/4HANA conversion journey.
• Risk Mitigation & Change Management:
• Conducted multiple user enablement and training sessions to ensure smooth adoption.
• Adopted an incremental testing approach to validate all custom integrations and ensure system readiness.

The Impact

• Future-Ready IT Landscape: Migrated from SAP ECC 6.0 to S/4HANA 2023, eliminating end-of-support risks and ensuring a future-proof digital backbone.
• Streamlined Integrations: Delivered a clean core integration framework for 350+ integration objects and 35+ non-SAP applications through CPI.
• Unified User Experience: Consolidated a fragmented FIORI landscape into a modern, embedded FIORI environment, enhancing usability and performance.
• Process Efficiency: Enabled automation and real-time analytics through S/4HANA innovations and SAP Analytics Cloud.
• Operational Agility: Standardized business processes across multiple geographies, driving efficiency, compliance, and faster decision-making.
