    We migrated a heavily customized ECC landscape to a modern S/4HANA architecture, simplifying finance, procurement, production and warehouse processes while enabling real-time reporting.

    The Challenge

    Years of ECC customizations lengthened month-end close, delayed reporting and inflated module-level integration costs. The gap between production planning and procurement caused recurring stock and cost variances.

    Our Approach

    • Value/complexity analysis of existing processes and customizations (Brownfield vs Greenfield decision).
    • Data quality assessment and master data cleansing workshop.
    • Test strategy with isolated sandboxes for unit, integration, load and UAT cycles.
    • Cutover and fallback plan with a controlled 36-hour go-live window.

    The Solution

    • Reimplementation of FI/CO, MM, SD, PP and EWM on S/4HANA 2022.
    • Role-based Fiori launchpad dashboards.
    • E-invoice and banking integrations rebuilt on SAP BTP.
    • Real-time operational reporting layer on Power BI.

    Results

    • 40% lift in operational efficiency.
    • Month-end close reduced from 6 days to 2.
    • 22% reduction in stock variance.
    • Manual reporting effort cut from 18h/week to 3h/week.
    "Smartia treated the migration as a real process transformation, not just a technical lift-and-shift. Our close speed changed our operating rhythm."
