  title: Ramp Locate Department Spend
  summary: Pull departments, users, and transactions to roll spend up by department.
  description: >-
    Builds the datasets needed to roll transaction spend up to a department.
    The workflow lists departments, then lists users so each user's
    department_id can be joined to a department, and finally lists transactions
    for a date window so each transaction's user_id can be traced through the
    user to its department. The three lists together let a caller compute
    per-department spend for the period. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
