  title: SAP BI Tools Provision a SAC User
  summary: Look up a SAP Analytics Cloud user by userName via SCIM 2.0 and create the user when no match exists.
  description: >-
    An idempotent SCIM 2.0 provisioning pattern for SAP Analytics Cloud. The
    workflow searches the user directory with a SCIM filter on userName and
    branches: when a matching user already exists it reads that user's detail,
    and when no match is found it creates a new user from the supplied profile
    attributes. SAP Analytics Cloud 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.
