  title: Oracle EBS Item Availability Check
  summary: Resolve an item by number, read its on-hand quantity, and branch on stock availability.
  description: >-
    An Oracle Inventory availability flow. The workflow resolves an inventory
    item by its number in an organization, reads on-hand quantities for it, and
    branches on whether stock is present to report the item as available or out
    of stock. Each step inlines its request so the availability check can be
    executed without opening the OpenAPI source.
