Relationships are the heart of Power BI modeling, and Power BI Desktop has a way to help and identify the relationships based on the source, or the data. However, often, this ability to automatically detect a relationship is more troublesome than helping, especially when you deal with tables that are not designed for reporting. In Read more about Power BI Design Tip: Disable the Auto-Detect Relationship[…]
Often you do the transformation in Power Query using the graphical interface, but having the formula bar visible, makes it much easier to understand or change the transformations. In this short blog and video, I’ll explain that. Power Query transformations In Power BI, we use Power Query a lot for transformations, but mostly using the Read more about Power BI Quick Tip: the Formula Bar in Power Query[…]
I have previously explained a number of use cases for dataflows. One really useful case for it is to use dataflow for slow data sources. In this short article and video, I’ll explain how this works. What is a dataflow? Dataflow is a Power Query process that runs in the cloud and stores the result Read more about Dataflow: a remedy slow data sources in Power BI[…]
It is not possible to change a linked entity in a dataflow in Power BI. Linked entities has to be modified only in the dataflow in which they are created. However, sometimes, you need to do a small modification to the linked entity in a chained dataflow. There is a very simple trick, In this Read more about How to modify a linked entity in Power BI dataflows[…]
In the previous article and video, I explained a method that you can use to have real-time calculations in a Power BI streaming dataset. The calculations done that way are limited though because it is using the Q&A feature of Power BI. If you are after a complex calculation then DAX can definitely help. In Read more about Writing calculations on a real-time streaming Power BI dataset using DAX measures[…]
If you use a streaming dataset in Power BI, you cannot download the Power BI file, and you cannot open it using Power BI Desktop. This means that you are limited not to use calculations in a streaming dataset. However, there is a small trick which you can use and can be helpful. I will Read more about How to write simple calculations in a Power BI streaming dataset?[…]
Do you have a Power BI dataset that gets data from a dataflow? have you ever thought; “can I get the dataset refreshed only after the refresh of dataflow completed and was successful?” The answer to this question is yes, you can. One of the recent updates from the data integration team of Power BI Read more about Streamline Power BI Refresh: Refresh dataset after a successful refresh of dataflow[…]
Dataflow is the data transformation service in Power BI, and also some other Power Platform services. Data Warehouse is the cloud storage and also compute engine for data. I often get this question that: “Now that we have dataflow in Power BI, should we not use the Data warehouse? What are the differences? which is Read more about Power BI Dataflow vs Data Warehouse: Which one to choose?[…]
With the DirectQuery to Power BI or Azure analysis services dataset, there are some limitations on the way that RLS (Row-level security) works. Considering that I have written a book and many blogs on this subject, It was fair to have a look at how this works. In this blog and video, you will learn Read more about Row-Level Security on a DirectQuery to Power BI dataset composite model: My Findings[…]
In my previous article and video, I explained why DirectQuery for a Power BI dataset is an important feature. In this blog and video, I explain how this feature works step by step. Prerequisite Before understanding how this feature works, I recommend reading below to understand WHY this is a game-changing important feature: Not from Read more about DirectQuery for Power BI dataset: How does it work?[…]
