Brownfield ECC to S/4HANA Conversion Across Procurement, Finance, and Warehousing

Company Overview

A municipal government using SAP across procurement, finance, payroll, warehousing, and service delivery throughout its geography. The landscape spanned supply chain, finance, warehouse management, supplier relationship management, procurement, business intelligence, HANA, and SuccessFactors, and the organization set out to upgrade the underlying platform without starting over.

Before: An Aging ECC Landscape Serving City Operations

• Core municipal functions ran on SAP ECC, which was due for upgrade across procurement, finance, warehousing, and human resources.
• Inventory distribution from the central warehouse out to smaller warehouses across the city followed a model more complex than it needed to be.
• Legacy data had to be carried into the new system, which required a migration approach built for this specific landscape rather than a generic one.
• Reporting gave limited real-time insight into city operations, which slowed decision-making and made expenditure harder to track.

The Solution

An end-to-end brownfield conversion moved the landscape from ECC to SAP S/4HANA, including S/4HANA on-premise, across procurement, finance, warehousing, and human resources. Delivery drew on subject matter expertise across supply chain, extended warehouse management, data services, finance, and business intelligence in a municipal government context, with the supplier and talent management platforms implemented to industry best practice. The inventory distribution model was simplified from the central warehouse to the smaller sites across the city, a unique data migration strategy was developed to move legacy data into S/4HANA, and the programme ran on an agile model through to go-live.

After: An Integrated Platform with Real-Time Operational Insight

• Fully integrated solution delivered for municipal operations, built to meet compliance requirements across the organization.
• Real-time reporting and analytics established across city operations, enabling data-driven decisions and faster response to issues.
• Transparency improved in government operations, making expenditure easier to track and performance easier to monitor.
• Materials planning and inventory holding handled across multiple sites within a single system.
• Successful go-live of the complete solution using an agile delivery model.

Efficiency Gains

• Inventory distribution simplified from the central warehouse to smaller sites across the municipality.
• Legacy data moved into S/4HANA through a migration strategy built for this landscape.
• Procurement, finance, warehousing, and human resources brought onto one platform.
• Timely delivery of new features and functionality throughout the program.
