AI-powered purchase order redesign leveraging Amazon Bedrock agents to automate intake, validation, and approval workflows across Oracle EBS. Three autonomous agents (intake validation, tracking, closure) orchestrate email ingestion, business rule enforcement via Lambda/SQS/EventBridge, and Oracle PO/AP integration through REST APIs or managed RPA. The architecture decouples human-in-the-loop approvers from operational bottlenecks, enabling procurement teams to process requisitions at scale while maintaining audit trails and compliance. Fork this diagram to customize agent prompts, add additional approval tiers, or integrate alternative ERP systems. Security layer includes IAM, KMS, Secrets Manager, and VPC isolation for sensitive financial data.
