  title: Oracle EBS Customer Receipt Application
  summary: Find an open AR invoice for a customer, then check for a matching cash receipt.
  description: >-
    An Accounts Receivable collections flow for Oracle EBS. The workflow lists
    open AR invoices for a customer, reads the first open transaction, and
    branches on whether a cash receipt already exists for that customer to
    report the balance as settled or outstanding. Each step inlines its request
    so the receipt-application check can be executed without opening the
    OpenAPI source.
