If you don’t have a Power BI Premium capacity license, then you are limited to refresh your dataflows up to eight times a day, with the frequency of 30 minutes. The good news for you is that you have a way to do unlimited refreshes and with whatever frequency you like using Power Platform Dataflows. Read the rest of this blog article to learn how.
What is Dataflow?
In the world of Power BI, You can separate the data transformation layer using Dataflows. Dataflows can run one or multiple Power Query scripts on the cloud and store the result into Azure Data Lake. The result of the dataflow (which is stored in Azure Data Lake) can then be used in a Power BI dataset using Get Data from Power BI dataflows. If you want to learn more about Dataflows, I highly recommend reading my dataflows series that starts with this article.
Creating Power Platform Dataflows
Dataflow is not only a concept for Power BI, but It is also available as Power Platform dataflow. You can check out one of the announcements of features added in Power Platform Dataflows by Miguel Llopis (one of the product managers of the Data Integration team at Microsoft), here. You can create Power Platform Dataflows, very similar to the way that you create Power BI dataflows. The only difference at the beginning is where you create it. Power BI dataflows are created in Power BI service, Power Platform Dataflows can be created in Power Apps (or Power Platform) portal.
Login to Power Platform Portal here.
Then go to Dataflows under the Data section,
Start a New dataflow
just provide a name for the dataflow, and then create
At this step, you can either go ahead and get data from anywhere you want or use Blank Query and copy a Power Query script from Power BI Desktop into here.
after preparing your queries, you can go to the step of loading it.
Load to Entity
The load to entity step in Power Platform Dataflows is a bit different from Power BI Dataflows. In Power BI Dataflows, the result will be loaded into CSV files into Azure Data Lake, so no more configuration is needed. However, Power Platform Dataflows stores the data into CDS (Common Data Services), and you have to select the entity you want to load this data into it.
You can either choose one of the existing entities or create a new entity, then map fields. Because these are CDS entities, there are some rules for having key fields, name fields, etc. If you don’t know what the CDS is, and where it stores the data, read my article about CDS here.
Refresh Settings
After setting up the load to entity and mapping fields correctly, you will get into the Refresh settings. This is where you can refresh your dataflow even with the frequency of a minute. You can refresh it as many times as you want. You are not limited to eight times or even 48 times a day.
Refresh as much as you want
Here you can see the frequency of the test dataflow that I set up, which ran every minute.
What about Licensing?
I know what you are going to ask now! What about licensing? What type of license do you need for this? Well, for Power Platform dataflows, you don’t need a Power BI license at all, not Premium, not even Pro. You do need, however, to have a Power Apps license. at the time of writing this blog post, there are two options, $10 a month, and $40 a month. Both of these can be cheaper than Power BI Premium if you are a single user (or even a few users). The main difference between the two plans of Power Apps, as I see is the database and file size for CDS;
How to use the results in Power BI?
You can use the result of dataflows in Power BI (similar to the way that you can use the result of Power BI dataflows in Power BI). You need to Get Data from Power Platform Dataflows.
However, at the time of writing this blog post, this feature is still beta and under development, and might not show the Power Platform dataflows.
Another option is also to get data from the Common Data Service. (Because Power Platform Dataflows stores the data into CDS)
Note that Power BI Dataset Refresh Limites Still Applies
Having a Power Query script that can refresh even every minute is great. However, you have to note that the dataflow refresh is different from the dataset refresh. If you use the result of the dataflow in a Power BI dataset, Still you need to get your dataset refreshed, and that means you are limited to eight times a day or 48 times a day or API refreshes depends on your Power BI license limits.
However, having the ability to refresh even the dataflow more frequent, still can be useful for some scenarios. I bet if you came to this post by searching for such functionality, you have some ideas about that already
