  title: SAP BI Tools Export Model Fact Data
  summary: Discover a SAC export model, read its OData metadata, and pull a filtered, paged page of fact data.
  description: >-
    A data-extraction pattern for the SAP Analytics Cloud Data Export API. The
    workflow lists the providers (models) available in the sac namespace,
    reads the OData metadata document of the first model to understand its
    structure, and then pulls a filtered, top-limited page of fact data from
    that model. The Data Export API uses OAuth 2.0 bearer authentication, so no
    logon token is threaded between steps. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
