  title: SAP BI Tools Export Dimension Master Data
  summary: Discover export namespaces and providers, read a model's master data overview, then pull a named dimension's master data.
  description: >-
    A master-data extraction pattern for the SAP Analytics Cloud Data Export
    API. The workflow lists the available export namespaces, lists the
    providers (models) in the first namespace, reads the master data overview
    of the first model, and then pulls the master data member list for a named
    dimension within 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.
