Key Steps in the Epicor MRP Process
The Epicor MRP Process follows a sequence that converts demand into planned supply actions. Each stage contributes to the accuracy and timing of the resulting recommendations.
- Collect demand: Review customer orders, forecasts, and production requirements to establish the quantities of finished products and components needed.
- Explode the bill of materials: Identify the raw materials, subassemblies, and components required to manufacture each planned product.
- Evaluate existing supply: Check usable inventory, allocated stock, open purchase orders, and scheduled manufacturing receipts.
- Calculate net requirements: Compare gross requirements with available inventory and incoming supply to determine additional material quantities.
- Schedule supply: Apply lead times, order policies, and required dates to recommend purchasing, production, or rescheduling actions.
- Review and release actions: Planners examine recommendations and coordinate approved orders or manufacturing activities with the relevant teams.
These steps help align material availability with production needs. The Mrp Module provides the broader planning framework, while the individual planning steps turn demand and supply records into operational decisions.
Demand, Inventory, and Supply Calculations
The process depends on accurate demand and supply information. Mrp Demand includes requirements generated by customer orders, forecasts, and dependent demand for components used in finished products. When production quantities change, the requirements for associated components may also change.
A simplified net material requirements calculation is:
Net Material Requirement = Gross Material Requirement − Available Inventory − Scheduled Receipts
Assume a manufacturer requires 1,000 component units for scheduled production. It has 250 usable units in inventory and 450 units scheduled to arrive before the materials are needed.
- Gross material requirement: 1,000 units
- Available inventory: 250 units
- Scheduled receipts: 450 units
- Net material requirement: 1,000 − 250 − 450 = 300 units
The manufacturer needs an additional 300 units to meet the planned requirement, assuming the existing stock and scheduled receipts are available for the relevant production dates. Actual recommendations may also account for safety stock, scrap allowances, minimum order quantities, and configured lot-sizing rules.
Planning Outputs and Operational Decisions
The Epicor MRP Process generates planning recommendations that help teams decide what to buy, what to manufacture, and when supply actions should occur. Suggested purchase orders help purchasing teams coordinate supplier deliveries. Planned manufacturing jobs help production teams organize work around component availability and required completion dates.
Rescheduling recommendations can identify when existing orders should move forward or backward to better match changing requirements. Planners can also review material shortages, excess supply, and changing demand before confirming purchasing or production actions.
For example, a manufacturer receives a new customer order that increases demand for a particular assembly. MRP recalculates the component requirements, checks inventory and incoming deliveries, and identifies the additional materials needed. Purchasing can then coordinate supplier orders while production adjusts the job schedule to support the customer commitment.
Integration with Epicor ERP and Procurement
The Epicor ERP environment connects material planning with inventory, purchasing, production, sales, and related business records. Accurate integration helps ensure that changes in orders, receipts, and inventory are reflected in subsequent planning decisions. Manufacturers extending their epicor ERP environment can also connect finance workflows with enterprise data to coordinate operational transactions and financial records.
Procurement controls complement MRP recommendations by defining how requisitions, approvals, supplier selection, and purchase orders are managed. The EDI Purchase Order Process: Standards & Compliance Guide explains how electronic purchasing documents support standardized exchanges and transaction records. The Purpose of Purchase Order Process: Business Outcomes Guide provides further context on how purchase orders establish authorization, supplier commitments, and spend visibility.
Hyperbots Platform supports company-specific ERP integrations, workflows, user roles, and general ledger structures through no-code configuration. Its Integrations List page describes connectivity with enterprise systems that enables coordinated data exchange. Process Specific Capabilities provide domain-trained AI automation for defined finance workflows, while Ready to Deploy Capabilities combine pre-trained agents, ERP connectors, and configuration options for finance tasks.
Finance Impact and Continuous Process Improvement
Material planning influences purchasing expenditure, inventory investment, production continuity, and working capital. When planners can anticipate material requirements, finance teams gain better visibility into upcoming purchasing commitments and the timing of cash outflows. Procurement and production teams can coordinate their priorities around the same demand and supply information.
Manufacturers can improve planning quality by maintaining accurate inventory records, reviewing bills of materials after product changes, validating supplier lead times, and monitoring shortages and rescheduling recommendations. Regular coordination between planning, purchasing, production, and finance helps keep assumptions aligned with actual operating conditions.
Self Learning Capabilities describe how Hyperbots co-pilots use human actions and feedback to adapt workflows and refine decisions in supported finance processes. Separately, Finance Copilot Architecture: 60% to 99% AI Accuracy explores how domain training, reusable agents, and coordinated workflows can improve AI accuracy. These finance automation approaches complement material planning by supporting associated financial processes, rather than replacing the core MRP calculations.
Summary
The Epicor MRP Process translates demand into material requirements and time-based supply recommendations using inventory, bills of materials, scheduled receipts, and lead times. Its outputs guide purchasing, production scheduling, and rescheduling decisions. Accurate data, coordinated procurement controls, and integration with the wider ERP environment help manufacturers manage inventory investment, anticipate purchasing needs, and support operational and financial performance.
