WORK HISTORY
ERP & Manufacturing Systems Analyst SAP s 4hana Mes Wms Integration @SK battery America
KY, US
Joint venture between Ford and SK ONLed end-to-end ERP process design, integration, and stabilization across manufacturing, logistics, finance, and sales in a large-scale battery manufacturing environment.Drove major improvements in cost accuracy, inventory integrity, and production visibility by aligning ERP with MES, WMS, EDI, and external planning systems.Key contributions include- Implemented consumption-based material cost evaluation, reducing distortion between actual and standard costs and improving WIP and finished-goods cost accuracy- Standardized non-production inventory movements by defining movement-type-based G/L accounts and cost objects, enforcing controlled logistics flows through MES/WMS- Improved raw material standard cost management to reflect market volatility, stabilizing manufacturing costs that represent 70–80% of total product cost- Designed MRP-driven raw material supply planning, improving visibility and efficiency of procurement and inbound logistics- Enhanced MES–ERP production result integration, including exception production handling and weekly-based production order management- Integrated customer EDI (forecast, shipping schedules, returns) into Sales & Distribution processes, enabling automated Sales Order creation and delivery follow-up- Built a structured pricing master framework aligned with headquarters standards, preparing the system for MaSS integration- Improved system reliability by implementing BizTalk database redundancy and strengthening interface monitoring- Supported financial operations through AUC asset settlement automation and lease accounting solution deploymentActed as a key bridge between business users, manufacturing operations, IT infrastructure, and external vendors, ensuring stable production operations and accurate financial reporting in a production-critical environment.

ABOUT SUNNY SMITH
I am an ERP & Manufacturing Systems Analyst with hands-on experience supporting production-critical manufacturing environments. My work focuses on designing, integrating, and stabilizing ERP systems connected with MES, WMS, EDI, and financial systems, ensuring accurate data flow from the shop floor to financial reporting.I have led and supported system improvements across Materials Management (MM), Production Planning (PP), Controlling (CO), Sales & Distribution (SD), and Finance, with a strong emphasis on inventory accuracy, cost transparency, and manufacturing continuity.In my role, I improved material consumption and cost evaluation processes by enabling consumption-based cost calculations, reducing gaps between actual and standard costs, and improving WIP and finished goods cost accuracy. I also standardized non-production inventory movements by defining movement-type-based G/L account and cost object rules, ensuring that all material movements were system-controlled through MES and WMS, not manual ERP entries.I worked extensively on raw material cost management, allowing more realistic standard cost estimation to reflect market volatility—critical in environments where raw materials account for 70–80% of total manufacturing cost. This significantly reduced cost distortion caused by WIP.On the logistics side, I implemented MRP-driven raw material supply planning, integrated purchasing and warehouse processes through WMS, and improved inbound, transfer, and issue flows to maintain inventory integrity across systems.I also supported customer-facing processes, integrating EDI-based forecasts, shipping schedules, and returns into ERP Sales Orders and delivery workflows. Additionally, I helped build a structured pricing and sales management framework aligned with headquarters standards, enabling scalable and consistent pricing operations.Beyond functional configuration, I actively collaborated with manufacturing, accounting, IT infrastructure, and external vendors, troubleshooting real-time production issues, supporting month-end close, and improving interface stability through middleware enhancements such as BizTalk redundancy.My strength lies in bridging manufacturing operations and enterprise systems, translating real-world production and logistics processes into stable, auditable, and scalable system solutions.
