Support Dataflow connections to SQL Server Analysis Service (SSAS), which desktop data sets allow users to do. At the moment, dataflow does not even support the use of a copied M script from desktop...
SSAS connector is available in Power BI to create datasets but not in Dataflow so we can't create SSAS datasets via Dataflow.
This looks disappointing as the connectors are not in sync with in Power BI between Power BI report dataset with Dataflow dataset.
Please add this connector.
