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?[…]
The news of the latest update of Power BI Desktop, December 2020, is now everywhere. Especially the most exciting feature of all is the DirectQuery for Power BI datasets and analysis service, or in other terms composite model for Power BI datasets. However, you might ask, what that mean? what is it? and how it Read more about DirectQuery for Power BI datasets and Analysis Services. The composite model with Analysis Services. What is it and why it is a big deal?[…]
Get data from a Power BI dataset is creating a live connection, which is the recommended way, because you will get the entire model. However, sometimes you want to import the data from the model so that you can add other things to it (like another data source). The ability to have a composite model Read more about How to IMPORT data from a Power BI dataset – Premium-only[…]
One of the questions I normally get after presenting about aggregations in Power BI is that, does the aggregation works only for Composite mode and in scenarios to speed up the DirectQuery? or does it work in import mode as well? This article is about this question and shows how you can speed up your Read more about Aggregation to speed up the performance of a Power BI report even if all IMPORTED[…]
Dataflows are useful for many scenarios when dealing with Power BI. One of their big advantages is the data source isolation and anything that comes with that. Benefits of such architecture are many, including datasets independent from the data source changes, and managing security in another layer from the data source. In this article, I’ll Read more about Power BI data source isolation using dataflows. How is it and what are the benefits?[…]
In the previous article, I explained how to implement a dynamic row-level security pattern when you have a value that you want to exclude. However, what if you want to EXCLUDE at some scenarios and INCLUDE in some others? What if you want to have a role saying access to everything but New Zealand, and Read more about Dynamic Row-Level Security in Power BI with Exclude and Include Rules[…]
Sometimes when you apply the dynamic row-level security, you want to have the criteria as NOT EQUAL and NOT IN. This can be a bit tricky in the dynamic implementation of RLS, because the relationship behavior is normally the opposite. In this article I’ll explain how you can do that. Introduction I have written many Read more about Dynamic Row-Level Security in Power BI with NOT IN or NOT EQUAL Rule[…]
If you have a visual in the Power BI, that based on some selections of a slicer it might return nothing, depends on the visual, you might get a blank visual, or some other types of improper view. In this blog, I share a simple trick that you can use to have an alternate message Read more about Showing an alternate text when no data available in a Power BI chart visuals[…]
