Frequently asked questions

DirectQuery is not working for me in Power BI—what should I do?

To get DirectQuery to run, you need to have Power BI Premium and adjust a few configuration items in your Power BI workspace. These actions are explained in the dataflows premium features article.

My dataflow table doesn't show up in the dataflow connector in Power BI

You're probably using a Dataverse table as the destination for your standard dataflow. Use the Dataverse/CDS connector instead or consider switching to an analytical dataflow.

There's a difference in the data when I remove duplicates in dataflows—how can I resolve this?

There could be a difference in data between design-time and refresh-time. We don't guarantee which instance is being kept during refresh time. For information on how to avoid inconsistencies in your data, go to Working with duplicates.

I'm using the Dataflow connector in DirectQuery mode—is case insensitive search supported?

No, case insensitive search on columns isn't supported in DirectQuery mode. If you need to use case insensitive search, you can use import mode instead. For more information, go to DirectQuery in Power BI.

I'm getting data via the dataflow connector, but I'm receiving a 429 error code—how can I resolve this?

When you are receiving an error code 429, it's possibly due to exceeding the limit of 1000 requests per minute. This error typically resolves by itself if you wait a minute or two after the cooldown period ended. This limit is in place to prevent dataflows and other Power BI functionality from having a degraded performance. Consequences due to the continued high load on the service might result in additional degraded performance, so we ask users to significantly reduce the number of requests to less than 1000 (limit) or fix your script/model to this specific limit (1000) to efficiently mitigate impact and avoid further issues. You should also avoid nested joins that re-request dataflow data; instead, stage data and perform merges within your dataflow instead of your semantic model.
