  title: SAP BI Tools Schedule and Poll the BI Inbox
  summary: Log on, schedule a document for immediate execution, then poll the BI Inbox until the completed instance is delivered.
  description: >-
    Automates a schedule-and-wait reporting pattern on the BI Platform. After
    authenticating, the workflow schedules a known document for immediate
    execution and then repeatedly polls the authenticated user's BI Inbox,
    branching back to poll again while the inbox is still empty and ending once
    items are present. The logon token captured at logon is supplied on every
    subsequent call via the X-SAP-LogonToken header. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
