Connect Live - SSAS - Update Frequency

We have an enterprise data gateway succesfully setup with live connections to SQL Server, SSAS MD, and SSAS Tab.  When viewing the refresh history, it shows that the refreshes are happening roughly e...

wmorris20 So when you refresh the model, and you interact with the report in the Service, what is the result? Do you see the new value, or not until this "refresh" happens?

I would expect that you should see the new value when you interact with your report, regardless of this refresh history.

I am also assuming that the only reason you see this on a live connection is the cache that supports the dashboard tiles is on this 30 minute schedule...

If either of the above are not correct, or not what you are seeing, I'm very interested...

I added a slicer to the report thinking that it had to be a literal interaction and not just refreshing the page/report, but that didn't work either.  Here are some examples using the Adventure Works data and manipulating sales amount:

On-Premise Version (Desktop):

 

 

 

 

Power BI Online after Refresh History shows update:

    Hi wmorris20,

     

    As far as I know, if we connect to on-premise data sources use live connection or DirectQuery mode, when we interact with a visualization, queries are sent from Power BI directly to the database. Updated data is then returned and visualizations are updated. It's corresponding to the results which you have found. As schedule refresh is not supported in this scenario, we are not able to set refresh frequency. For more information, please refer to this article: Live connections and DirectQuery to on-premises data sources.

      Qiuyun, when in DirectQuery mode (via SQL Server live connection), the data updates on interaction as you stated.  The issues is when I have a live connection interacting with SSAS.

       

      Thanks,

      Ward

        Hi wmorris20,

         

        I can reproduce the issue with SSAS tabular in live connection intermittently. And I already report this issue internally, will update here once I get any feedback.

    wmorris20 I read your question in this way: You are updating the SSAS model and when you then interact with the report in the Service (Use slicer, interact with visuals for filtering purposes) the updated information is not showing. -> If this is the case, this is a bug and you should submit this as an issue.

    I've confirmed with the team that this should interaction should show the latest information, and the caching process that you see in the history shouldn't be the only time the data is refreshing.

      Correct, I have a confirmed updated model (via Power BI Desktop); however, the online version via data gateway is not showing updated data until the (~30 min) refresh happens.

        wmorris20 That is a bug. It should be showing you the updated data as you interact with it.
