Limitation to Direct Query Refresh? https://github.com/microsoft/PowerBI-JavaScript/wiki/Embedding

Are there any limitation to Power BI direct query refresh? 

 

Document link : https://github.com/microsoft/PowerBI-JavaScript/wiki/Embedding---Basic-interactions

 

 

Refresh the underlined data of a report without reset current filters and user interactions. Works only in Direct Query mode. The code below assumes element with id myReport already contains an embedded report:

var element = document.getElementById('#myReport');
var report = powerbi.get(element);

report.refresh()
  .catch(error => { ... });

    Hi Anonymous ,

     

    There are currently a few limitations to using DirectQuery:

    • All tables must come from a single database, unless using composite models

    • If the Query Editor query is overly complex, an error will occur. To remedy the error you must either delete the problematic step in Query Editor, or Import the data instead of using DirectQuery. For multi-dimensional sources like SAP Business Warehouse, there is no Query Editor

    • Time intelligence capabilities are not available in DirectQuery. For example, special treatment of date columns (year, quarter, month, day, so on) is not supported in DirectQuery mode.

    • Limitations are placed on DAX expressions allowed in measures to ensure that queries sent to the underlying data source have acceptable performance.

    • There is a one-million-row limit for returning data when using DirectQuery. The limit does not affect aggregations or calculations used to create the dataset returned using DirectQuery, only the rows returned. For example, you can aggregate 10 million rows with your query that runs on the data source, and accurately return the results of that aggregation to Power BI using DirectQuery as long as the data returned to Power BI is less than 1 million rows. If more than 1 million rows would be returned from DirectQuery, Power BI returns an error.

      thank you for your prompt reply. Is there a limitation to the number of refreshes? Our POC has embedded Power BI dashboard in a .net application and when data is updated by user, we want to trigger a refresh.

        Hi Anonymous ,

         

        The Data Refresh API shares the same limitation(8 times per day) with "Schedule Refresh" with a Pro license. After exceeding the limitation, the API call would get the response saying "Number of refresh requests in last 24 hours exceeded limit".

        If you'd like to lift this limitation, you may have to buy a premium license(48 times per day).
