DRP is a time-phased supply chain planning process that decides what finished goods to send, when to send them, and where to position them across a distribution network — using demand forecasts, inventory data, safety stock, and lead times.
Distribution Requirements Planning (DRP) is a time-phased supply chain planning process that decides what finished goods to send, when to send them, and where to position them across a distribution network by using demand forecasts, inventory data, safety stock, and lead times. For supply chain professionals, distribution and logistics planners, manufacturing and operations managers, and businesses using or evaluating ERP platforms such as LOGIC ERP, it provides a practical way to keep multi-location inventory aligned with customer demand while reducing excess stock, storage costs, and stockouts.
In today’s volatile market environment marked by disruptions such as the pandemic, port congestions, and logistics challenges accurate demand forecasting and distribution network optimization have become indispensable for companies operating across multiple locations in India and globally. DRP fits seamlessly within enterprise resource planning (ERP) systems like LOGIC ERP, linking demand forecasting, current inventory levels, and distribution planning to synchronize operations and improve product availability, customer service, and supply chain resilience. This guide explains what DRP includes, how the step-by-step process works, how DRP tables and time-phased planning support decisions, how it connects with MRP and ERP, the common challenges and solutions, industry use cases, implementation best practices, advanced concepts, and key FAQs.
Explore the detailed benefits, processes, examples, and how DRP integrates with MRP and ERP systems in the sections ahead.
Distribution Requirements Planning (DRP) is a time-phased planning method that uses demand forecasts, current inventory data, optimal safety stock levels, and replenishment lead times to create detailed replenishment schedules and replenishment plans for each distribution center (DC) and warehouse. DRP focuses on finished goods, managing inventory flows across multiple echelons from central warehouses to regional DCs, local depots, and retail locations.
DRP extends the logic of Material Requirements Planning (MRP) downstream into the distribution network. While MRP concentrates on raw materials and components for production, DRP ensures that finished goods are available at the right place and time to meet customer demand.
Industries widely using DRP include FMCG, consumer electronics, pharmaceuticals, automotive, fashion/apparel, and grocery & food chains.
For example, an Indian FMCG company uses DRP to plan shampoo inventory across four regional distribution centers and 120 distributors, ensuring product availability aligns with sales forecasts and actual demand.
DRP, MRP, and ERP are complementary systems that collectively enhance supply chain and supply chain management efficiency.
Focuses on raw materials and components needed for production at manufacturing plants. It uses inputs like the master production schedule, bill of materials (BOM), and lead times to ensure timely material availability.
Manages the flow of finished goods between factories, warehouses, distribution centers, and retail locations, based on demand forecasts and inventory levels.
Platforms like LOGIC ERP integrate MRP, DRP, finance, procurement, sales, and warehouse management into a single database, enabling real-time data synchronization and streamlined operations.
Data flows from demand forecasts into DRP for finished goods planning, which in turn informs MRP for raw material planning within the ERP system. Inventory and order data are automatically synchronized to maintain consistency.
| System | Objective | Typical User | Supply Chain Level |
|---|---|---|---|
| MRP | Plan raw materials | Manufacturing | Upstream production |
| DRP | Plan finished goods distribution | Distribution and logistics | Downstream distribution |
| ERP | Integrate all business processes | Enterprise-wide | Entire supply chain |
Accurate DRP depends on clean, real-time data across the distribution network. Core elements include:
Demand Forecasts
Weekly or monthly forecasts by SKU and location, incorporating historical sales, promotions, seasonal demand, and market trends.
Current Inventory
Real-time stock on hand, in transit, and reserved at each distribution center and warehouse.
Safety Stock
Buffer inventory calculated based on desired service levels (e.g., 95–99%), demand variability, and replenishment lead times.
Replenishment Lead Time
Includes transport times, handling, customs clearance, and administrative delays (e.g., a 3-day lead time between central DC in Delhi and regional DC in Lucknow).
Lot Sizes and Order Constraints
Minimum order quantities, truckload capacities, pallet and carton rules.
Service Level Targets
Fill rate targets (e.g., 97%+), and on-time, in-full (OTIF) delivery goals by customer or channel.
Supporting master data includes location hierarchy, item master data, calendars, holidays, and dispatch cut-off times.
The DRP process is cyclical, typically run weekly or daily over a planning horizon of 8 to 26 weeks.
Demand Forecasting
Generate time-phased demand forecasts for each SKU-location using statistical models combined with sales input.
Inventory Analysis
Capture current inventory, goods in transit, open purchase or transfer orders, and blocked or damaged stock.
Net Requirements Calculation
Calculate net requirements per period as forecast plus safety stock minus projected available inventory.
Order Quantity and Timing
Apply lot-sizing rules (economic order quantity, minimum order sizes, truckload optimization) to determine planned order receipts and releases.
Capacity and Constraints Check
Verify warehouse capacity, transportation resources, loading docks, and labor availability.
Distribution Network Optimization
Rebalance inventory flows across plants, central DCs, regional DCs, and cross-docks to minimize costs while meeting service targets.
Review & Collaboration
Planners, sales, and logistics teams review exceptions such as stockouts or overloads and adjust plans accordingly.
Execution in ERP
Convert approved planned orders into actual purchase or stock transfer orders through ERP workflows like LOGIC ERP.
| Week | Forecast Demand | Projected Inventory | Scheduled Receipts | Planned Order Receipts | Planned Order Releases |
|---|---|---|---|---|---|
| Week 1 | 100 units | 150 | 0 | 0 | 0 |
| Week 2 | 120 units | 30 | 50 | 0 | 0 |
| Week 3 | 110 units | 0 | 0 | 100 | 100 |
| Week 4 | 130 units | 20 | 0 | 0 | 0 |
| Week 5 | 115 units | 5 | 0 | 120 | 120 |
| Week 6 | 125 units | 10 | 0 | 0 | 0 |
A DRP table is a time-phased grid central to the DRP process, showing inventory and order information across time buckets such as weeks or specific dates.
A distribution center in Mumbai manages a popular mobile phone model over 8 weeks, starting with 500 units on hand and a 1-week lead time from the central warehouse. As forecast demand reduces inventory, DRP suggests planned order receipts in week 4, which requires order releases in week 3 to meet demand on time.
Well-implemented DRP can reduce inventory levels by 15–30% while improving service levels, often pushing fill rates above 97% without overstocking.
For example, an Indian fashion retailer uses DRP within LOGIC ERP to smooth seasonal spikes around Diwali and Eid, improving customer satisfaction and reducing excess stock.
DRP is powerful but depends on data quality, process discipline, and organizational buy-in.
Track key performance indicators such as forecast accuracy, inventory turns, fill rate, on-time in-full (OTIF), and planning cycle time to monitor DRP success.
DRP principles apply universally but are tailored to industry-specific needs:
FMCG & Grocery
Manage perishable and non-perishable goods with short shelf life and frequent promotions; safety stock and lead times tuned to minimize waste.
Fashion & Apparel
Address strong seasonality and size/color complexity; push inventory by store profile ahead of festivals and new launches.
Pharmaceuticals
Meet regulatory requirements, batch tracking, and high service levels for essential medicines.
Electronics & Durable Goods
Prevent overstock and obsolescence of high-value SKUs by focusing inventory in regional DCs and urban markets.
E-commerce & Omnichannel Retail
Support fast delivery promises by positioning stock closer to customers in city hubs and dark stores.
For instance, a consumer electronics company completed a 6-month DRP rollout in 2025, reducing inventory by 20% and improving fill rates by 5%.
Implementing DRP requires a structured approach:
Includes data quality, executive sponsorship, cross-functional team, clear KPIs, and IT resources.
LOGIC ERP supports DRP with preconfigured templates, integrated demand forecasting, automated stock transfer order generation, and dashboards.
Mature organizations evolve DRP from basic to advanced demand-driven and network-optimized systems.
Replenishment based on forecasted demand; common in seasonal FMCG and fashion.
Replenishment triggered by actual consumption at downstream nodes (e.g., VMI, Kanban).
Combines buffers and dynamic adjustments based on product volatility.
Uses DRP outputs with cost data to evaluate DC locations, cross-docking, and transshipment strategies, balancing transportation costs, service levels, and inventory holding.
Include AI-enhanced demand forecasting, IoT data for real-time conditions (especially in cold chains), and scenario planning within ERP/APS integrated with DRP.
