1️⃣ Objective

Build a comprehensive, real-time dashboard leveraging SAP data (MM, WM/EWM modules) to provide operational visibility, predict stockouts, optimize inventory levels, and analyze warehouse efficiency metrics for supply chain decision-making.      

Key Goals:

✨Visualize key inventory metrics (turnover, fill rate, obsolete stock) in near real-time.
✨Implement predictive models for stockout risk and demand forecasting.
✨Analyze warehouse operations: picking/putaway efficiency, cycle time, and labor productivity.
✨Develop a user-friendly, interactive dashboard for supply chain managers.

2️⃣ Problem Statement

Organizations running on complex ERP systems like SAP often struggle to extract timely, unified, and actionable insights from their immense volume of inventory and logistics data. This leads to suboptimal purchasing, frequent stockouts, high carrying costs, and inefficient warehouse processes. A consolidated, intelligent dashboard is necessary to transform raw SAP transactional data into strategic business intelligence.

3️⃣ Methodology

The project will combine data extraction, warehousing, time-series modeling, and visualization:

Phase 1 — Data Extraction & Staging: Extract key data from SAP modules (MARA, EKPO, LIKP, MSEG, etc.) using an appropriate connector (e.g., SAP OData/Hana or third-party ETL).
Phase 2 — Data Modeling & Feature Engineering: Create star/snowflake schema in a data warehouse; calculate derived features like inventory turnover ratio, days of supply, and historical lead times.
Phase 3 — Predictive Modeling: Build time-series models (ARIMA, Prophet, or deep learning) for short-term demand forecasting and classification models (XGBoost) for stockout prediction.
Phase 4 — Dashboard Development: Create interactive visual dashboards to display current stock levels, inventory performance, forecast vs. actuals, and warehouse efficiency metrics.
Phase 5 — Performance Evaluation: Validate model accuracy and measure the impact of the dashboard on key operational KPIs (e.g., reduction in out-of-stock events).

4️⃣ Dataset

Core Entities:

SAP Material Management (MM): Material Master (MARA), Inventory Movements (MSEG).
SAP Warehouse Management (WM/EWM): Transfer Orders, Picking/Putaway activities, Labor utilization logs.
SAP Sales and Distribution (SD): Sales Orders, Deliveries (VBAK, LIKP, LIPS).
External: Historical market data, seasonal indices, promotional calendars (for forecasting).
