Run MRP When Demand Needs A Plan

Use MRP when inventory and purchasing teams need to know what should be built and what should be bought before orders or stockouts create urgency. MRP suggestions are live planning results until a user selects them and creates records.

Production Planning MRP page with horizon, include safety stock toggle, Run MRP button, summary cards, suggested work orders, and suggested purchase orders

​
Choose The Planning Inputs

  • Horizon: number of future days Arcus should consider when analyzing demand and required dates.
  • Include safety stock: adds safety stock targets to demand so replenishment can happen before stock reaches zero.
  • Run MRP: refreshes the live suggestions using current inventory, demand, BOM, work order, and purchasing data.
MRP suggestions are not records until you create them Running MRP does not create work orders or purchase orders by itself. The user must select suggestions and create them from the planning page.

​
Read The Summary Cards

  • Products analyzed: products included in the current planning pass.
  • Can build now: suggested work orders with all required parts available.
  • Waiting on parts: suggested work orders that need component replenishment first.
  • PO suggestions: purchase suggestions for components or products that should be bought.

​
Suggested Work Orders

A suggested work order means Arcus found manufacturing demand for a product that has an active BOM. Each suggestion shows quantity, start-by date, estimated cost, demand breakdown, and whether the required parts are ready.

  • Parts ready: components are available for the suggested quantity.
  • Waiting on parts: one or more components are short.
  • Demand breakdown: shows whether the need came from orders, forecast/run rate, dependent work order demand, or safety stock.
  • Open: starts the New Work Order page with the suggested BOM selected.
Do not create every suggestion automatically Use MRP as a planning proposal. Review quantities, dates, component shortages, vendor lead time, floor capacity, and existing POs before creating work orders or purchase orders.

​
Suggested Purchase Orders

Purchase suggestions are grouped by vendor when records are created. They are meant to close component or product shortages that MRP found inside the planning horizon.

  • Vendor: where Arcus expects the item to be purchased.
  • Quantity: suggested buy quantity needed to close the planning gap.
  • Order by date: date implied by lead time and expected need.
  • For work orders: shows which suggested builds are driving the purchase need.
No-vendor purchase suggestions need cleanup If a suggested purchase order has no vendor, add or fix the product’s purchasing setup before creating POs. Otherwise the draft PO may not be usable without manual cleanup.

​
Create Suggested Records

  1. Run MRP with the correct horizon and safety stock choice.
  2. Review the Suggested Work Orders section.
  3. Select only the work orders that should be created now.
  4. Review the Suggested Purchase Orders section.
  5. Select only the purchase suggestions that should be created now.
  6. Create the selected suggestions.
  7. Open the created work orders and purchase orders for normal review, approval, release, or vendor sending.

​
What Arcus Updates

  • Selected work order suggestions become draft work orders using the suggested BOM, quantity, and planned start date.
  • Selected purchase suggestions become draft purchase orders grouped by vendor.
  • Created records follow normal approval, release, receiving, billing, and accounting workflows.
  • MRP and inventory planning refresh after records are created so duplicate demand is reduced.

​
Common Blocks

  • No work orders are suggested: confirm the product has an active default BOM and demand inside the horizon.
  • Parts are always short: review component balances, open POs, safety stock, and component reorder setup.
  • Suggested quantity looks too high: check safety stock, open sales order demand, forecast/run-rate demand, and dependent demand from other work orders.
  • Create suggestions returns errors: create fewer suggestions, fix missing vendors, confirm locations, and retry.
  • MRP differs from the Reorder Report: MRP includes manufacturing demand and BOM dependencies, while the Reorder Report focuses on product-level reorder signals.

Bills of Materials

Create BOM recipes for assemblies, disassemblies, conversions, revisions, defaults, costs, and availability.

Work Orders

Create, release, start, complete, close, or cancel manufacturing work from active BOMs.

Supply and Demand

Review stockout pressure, demand signals, reorder timing, safety stock, and suggested reorder quantity.

Reorder Report

Find low-stock products, review vendor grouping, and generate draft purchase orders from reorder settings.

Create and Manage Purchase Orders

Create POs, add vendor items, receive inventory, and handle approval, cancellation, billing, and close-short blocks.

Manufacturing Reports

Review WIP aging, cost variance, build history, and component usage from work order activity.
