Infor LN Engineering Change Order and ECN Management
Engineering Change Management in Infor LN controls how product design modifications flow from engineering request through impact analysis, approval, and implementation across BOMs, routings, and active production orders. The ECM module, managed through sessions like tdisg0501m (Engineering Change Orders) and tdisg0101m (Item Revisions), ensures that design changes are systematically evaluated, approved, and executed with full traceability and minimal production disruption.
ECO/ECN Workflow and Approval Process
Infor LN Engineering Change Orders created in session tdisg0501m follow a configurable workflow from initiation through review, approval, and implementation phases. Each ECO specifies the affected items, the nature of the change (form, fit, function), the reason category, and the requested effectivity date. The approval workflow routes ECOs through engineering, manufacturing, quality, procurement, and finance stakeholders based on change classification and impact severity.
- Create Engineering Change Orders in tdisg0501m with change type classification, priority level, and target effectivity date
- Configure multi-stage approval workflows routing ECOs through engineering review, manufacturing feasibility, and quality impact assessment
- Define change classification categories: emergency, mandatory, cost reduction, and improvement with different approval paths per type
- Set up automatic notification to affected departments when ECOs are created, approved, or approaching implementation deadline
- Link ECOs to Engineering Change Requests (ECRs) in tdisg0401m to maintain traceability from initial request through implementation
BOM and Routing Revision Control
Infor LN manages item revisions through session tdisg0101m, linking each revision to specific BOM and routing versions. When an ECO is approved, new BOM and routing revisions are created with effectivity dates that control when the change takes effect. The system supports date-effective, serial-number-effective, and order-effective revision transitions, allowing precise control over when old components phase out and new components phase in.
- Manage item revision history in tdisg0101m with revision numbering, description, and linked BOM/routing version references
- Configure BOM effectivity in tibom0101m using date-effective, serial-number-effective, or production-order-effective transitions
- Set up routing version control in tirou0101m to phase in process changes aligned with BOM revision transitions
- Enable where-used analysis to identify all parent assemblies and end items affected by a component-level engineering change
Impact Analysis and Implementation Planning
Before approving an engineering change, Infor LN provides impact analysis tools that assess the effect on active production orders, open purchase orders, warehouse inventory, and customer commitments. Session tdisg0520m generates impact reports showing the quantity and value of affected inventory, the cost of implementing the change, and the schedule impact on open manufacturing orders. This analysis enables informed decision-making on change timing and obsolete inventory disposition.
- Run engineering change impact analysis through tdisg0520m to quantify affected inventory, open orders, and cost implications
- Configure obsolete material disposition rules for scrap, rework, use-until-depleted, or return-to-vendor options per change type
- Generate implementation schedules coordinating BOM switchover with procurement lead times and production order completion dates
