MANN+HUMMEL Advances Clean Core Strategy with SAP Cloud ERP Rollout

MANN+HUMMEL is standardizing its legacy systems onto SAP Cloud ERP as part of a broader modernization strategy to unify processes, improve reporting accuracy, and support future growth.

The filtration products manufacturer, which operates more than 80 locations worldwide, expanded rapidly with recent acquisitions, and was dealing with a patchwork of local ERP systems.

Arjun Prasad, Program Manager for SAP S/4HANA Cloud Business Transformation at MANN+HUMMEL, explains: “Each acquired company has its own DNA and its own business processes. Some used best practices, but not all. Our goal was to bring these companies together in a standardized, scalable ERP system.”

From ERP Sprawl to a Clean Core Strategy

Consolidating financial and operational data at the group level required manual extraction, normalization, and re-entry into reporting systems, limiting speed and transparency.

Inconsistent data and limited transparency were also disrupting routine operations. Prasad noted that in daily business the company encountered problems with transactions between group companies, where a part ordered by one entity could be labeled differently by the receiving company, and the effort required to clarify these frequently occurring scenarios was far too high.

By deploying a standardized chart of accounts and harmonized business processes within a public cloud framework, the company is establishing a clean, consistent foundation for reporting and analytics.

What This Means: Clean core enables scalable acquisition integration. Organizations pursuing growth through acquisitions must normalize processes and data quickly. A standardized SAP Cloud ERP template reduces onboarding friction, accelerates consolidation, and ensures financial and operational comparability from day one.

Reframing End-to-End Process Ownership

MANN+HUMMEL’s move to a clean core has also changed how the company views its end-to-end processes. Rather than managing finance, supply chain, and operations as largely local or siloed activities, the organization is increasingly approaching them as integrated value streams.

Standardized data structures and shared process definitions provide clearer accountability across order-to-cash, procure-to-pay, and intercompany workflows. “Previously, there were areas such as manufacturing, sales, purchasing, and supply chain. Now we are transforming these processes into end-to-end processes. For example, a customer order encompasses sales and finance, but one person is responsible for the entire process from order placement to payment receipt. If we want to change something, we coordinate it with this person and identify problems early on,” Prasad explained.

What This Means: High-quality data becomes a strategic asset. When master data is harmonized across entities, leaders shift from reconciling discrepancies to optimizing performance. Reliable, real-time data supports better production planning, cost control, compliance, and the design of new service models.

Turning Standardization into Measurable Results

With a unified ERP backbone, process performance can now be measured consistently across business units. For example, at the first deployment site, leadership gained clearer visibility into order-to-cash cycle times and intercompany transactions that previously required manual clarification due to inconsistent part naming and data structures.

Daily financial reporting, once dependent on extracting and reconciling data from multiple systems, is now produced within a standardized framework, giving managers timely insight to enforce governance and resolve bottlenecks earlier.

The standardized chart of accounts has also streamlined group-level consolidation. Instead of manually aligning different financial structures across acquired entities, new business units can now adopt a predefined template aligned to corporate standards. This template-driven approach reduces onboarding time for acquisitions and ensures that financial and operational metrics are comparable from day one.

The result is a more disciplined approach to managing global operations from end to end with increased transparency.

Rollout Progress and Future Expansion Plans

According to Prasad, higher-quality data is already improving decision-making at the Wiesbaden, Germany deployment site, where finance and operations teams now work from a single source of truth rather than reconciling conflicting records.

He added that the clean core approach positions the company to benefit more from ongoing SAP innovation and support, enabling smoother updates and stronger governance controls.

The rollout of SAP Cloud ERP is continuing across MANN+HUMMEL’s Life Sciences and Environment (LS&E) division.

Sweden and the United States are currently implementing the system, with Switzerland, Denmark, China, Austria, and the Netherlands scheduled to follow. In total, the transformation will span 21 locations across 13 countries. At the same time, LS&E continues to acquire companies that can now be integrated into the standardized ERP template more quickly and with less disruption.

Throughout the rollout, SAP’s support model has played a critical role in stabilizing and scaling the transformation. According to company leadership, the standardized cloud environment allows MANN+HUMMEL to adopt updates more smoothly, reduce reliance on custom fixes, and align more closely with SAP best practices. Access to ongoing innovation, structured guidance, and a predictable subscription model has helped the company manage risk during deployment.

What This Means: Public cloud lowers long-term transformation risk. Minimizing customizations strengthens upgrade resilience and simplifies governance. Continuous SAP innovation, predictable subscription economics, and structured support models help large enterprises scale transformation with greater confidence and lower technical debt.
