Custom Engineering Change Workflow with Server-Side Java Automation
An aerospace and defense manufacturer running Windchill PDMLink 12.1 had a rigid out-of-the-box ECO workflow that could not handle their multi-tier approval logic, conditional routing by part classification, or automatic ERP notification on release.
Problem
Standard Windchill workflow templates could not support conditional branching based on part type, cost impact threshold, or affected assembly level. Approval routing was done manually by email outside the system, with no audit trail.
Solution
Built a custom WorkflowProcessor in Java that reads part classification attributes and change impact metadata to auto-route approvals. Implemented OperationDelegate validators blocking promotion without mandatory sign-offs. Added a server-side event listener posting ERP notifications on lifecycle state change.
