  title: Oracle EBS Order-to-Cash
  summary: Check item availability, create a sales order, confirm it, then raise the AR invoice.
  description: >-
    A sell-side Oracle E-Business Suite flow. The workflow verifies on-hand
    inventory for the ordered item, books an Order Management sales order for a
    customer, reads the order back to confirm its flow status, and creates the
    matching Accounts Receivable invoice. Every step inlines its request so the
    order-to-cash chain can be executed without opening the OpenAPI sources.
