A planned order is more useful when the planner can answer why it exists

What Simor ERP makes available

Simor ERP includes MRP Pegging within advanced manufacturing. It works with products, BOMs, routings, production orders, work orders, inventory, purchasing, reorder settings, and cost analysis. The goal is not simply to generate orders; it is to make the relationship between requirement and response reviewable.

A planner can use that relationship to decide whether to expedite, delay, split, substitute, transfer, purchase, manufacture, or accept a shortage. Simor Soft can adapt planning views, filters, alerts, approvals, and integration around the customer's operating model.

The question hidden behind a shortage

A component may be short because of a customer order, forecast, safety-stock policy, another component's scrap, or a production date change. Without pegging, planners often treat all shortages alike and may expedite supply that does not protect the most important demand.

Multi-level manufacturing makes the explanation harder. A finished product creates dependent demand for subassemblies and raw materials. Each level has its own on-hand balance, lead time, lot size, calendar, and existing supply.

Example: two customers compete for one component

Two production orders require the same purchased component, but only one supplier delivery will arrive on time. Pegging should show which demands depend on that receipt and the dates at risk. The planner can then evaluate customer priority, alternative stock, substitute material, split production, or an expedited purchase.

If a sales order is cancelled, the linked planned supply should be reconsidered. It may still serve another demand or safety stock, but it should not remain merely because the original recommendation was never reviewed.

Signals that help a planner act

• Requirement date, supply date, and the number of days early or late.
• Demand source, priority, quantity, and remaining uncovered amount.
• Existing purchase, transfer, production, or planned supply.
• BOM level and parent demand that generated a component requirement.
• Firming, rescheduling, cancellation, and exception history.

Prove the plan can be explained

Create demand for a manufactured item with two BOM levels. Include insufficient stock, an open purchase order, a delayed work centre, safety stock, and a substitute component. Run planning, inspect pegging, change one date, and verify that the affected messages change without unrelated orders moving unexpectedly.

Test cancellation, partial supply, order multiples, scrap factor, lead-time changes, and simultaneous demand. A planner should be able to start from a planned order and reach its demand, then start from demand and identify expected supply.

Planning exceptions that change priority

The normal route is rarely where planning evidence fails, so these cases need an owner, permitted action, approval rule, and expected accounting or operational result before deployment:

• one supply order serves several demands
• a cancelled sale leaves surplus supply
• component scrap increases the requirement
• capacity delay changes a parent date
• substitute material is available at another site

Each MRP Pegging and Demand-Supply Traceability exception should state whether the record is corrected, reversed, held, rejected, or completed with an approved variance; the original event stays visible because a free-text note cannot govern a change to inventory, cash, payroll, obligations, or financial reporting.

Evidence behind each demand-supply link

A reviewer of planning evidence should reconstruct the outcome without memory or a private spreadsheet, which means preserving the relationship among these records:

• independent demand source
• dependent BOM requirement
• available and reserved inventory
• planned purchase or production supply
• pegging relationship and priority
• reschedule or cancellation message

Within MRP Pegging and Demand-Supply Traceability, identifiers, dates, status, user, source document, and correction history should remain consistent across screens and exports; attachments can support a decision, but they should not replace structured values that the ERP must validate, report, and reconcile.

Decision rights for planners and buyers

MRP Pegging and Demand-Supply Traceability crosses several responsibilities, so its workshop should name the decision owner, the person who performs the work, the reviewer, and the role that resolves an exception; without that separation, the screen may capture data correctly while the operating issue remains unowned.

• planner who reviews recommendations
• production scheduler who owns capacity dates
• buyer who acts on purchase supply
• sales team who understands customer priority

Responsibility for planning evidence does not require four different employees in every business, but it does require explicit authority when one person performs several tasks; approval thresholds and independent review can remain proportionate to value and risk.

Evaluate planning stability after rollout

Usage volume does not prove that planning evidence is working well; these operational measures can expose delay, rework, control failure, and avoidable manual effort:

• late demand exposure
• expedite recommendations
• planned orders without clear demand
• reschedule messages unresolved
• shortage value by customer priority

For MRP Pegging and Demand-Supply Traceability, baseline the measures before rollout and review them with the people doing the work; a worsening result may point to training, master data, integration, policy, or screen design, and the response should address that cause rather than add another workaround.
