As I mentioned earlier in Power BI online book, Power Query is a functional language. Knowing functions is your best helper when you work with a functional language. Fortunately Power Query both in Excel and Power BI can use shared keyword to reveal a document library of all functions. I’ve written about shared keyword almost Read more about Power Query Library of Functions; Shared Keyword[…]
Aggregation can speed up the performance of DirectQuery sourced tables significantly. To use it, firstly, you need to create an aggregation table. Secondly, you must set up proper storage modes for tables in the model. Finally, you have to configure the aggregation functions, which I will explain in this post. You can learn about aggregation Read more about Power BI Aggregations Step 3: Configure Aggregation Functions and Test Aggregations in Action[…]
In Microsoft Fabric, the Data Factory is the workload for ETL and data integration, and the Data Pipeline is a component in that workload for orchestrating the execution flow. There are activities in the pipeline, and you can define in which order you want the activities to run. In this article and video, you will Read more about Control the Execution Order and Output State in Fabric Data Pipeline[…]
Although this seems to be a simple thing to do, it is not a function that you can turn on or off. If you have a Dataflow that does the ETL and transforms and prepares the data, then to get the most up-to-date data into the report, you will need to refresh the Power BI Read more about Refresh Power BI Semantic Model After Dataflow Automatically[…]
One of the questions I often get these days is what are the benefits of Microsoft Fabric for Power BI users and developers. Questions like: “If I am not a data engineer or database developer, what are the use cases for Fabric for me?” or “What is in Fabric that I can leverage in my Read more about Where to Start Microsoft Fabric as a Power BI Developer[…]

Unfortunately, there isn’t a migration tool to convert your Power BI dataflow (gen1) to Microsoft Fabric dataflow (gen2). If you have Fabric capacity licenses, it just makes sense to do that migration because Dataflow Gen2 gives you data destinations into four destinations, which we don’t have in Dataflow Gen1. However, converting Gen1 to Gen2 isn’t Read more about Migrate Power BI Dataflow Gen1 to Fabric Dataflow Gen2[…]
Power BI offers a new type of connection to Microsoft Fabric Lakehouse or Warehouse, called Direct Lake. The Direct Lake connection acts like DirectQuery and won’t need the data to be refreshed. However, the Power BI semantic model has refresh settings that can be turned on or off. In this article and video, you will Read more about REFRAME in Power BI Direct Lake[…]
In the previous article, I explained SCD (Slowly Changing Dimension) and its different types. In this article, I’ll show you how to implement SCD Type 2 (one of the most common types) using Microsoft Fabric and Power BI. This article includes using Lakehouse, Dataflow, Warehouse, Data Pipeline, SQL Stored Procedures, Power BI Semantic model, and Read more about SCD Type 2 in Microsoft Fabric and Power BI[…]
If you want to use Power BI, Microsoft Fabric, or any other data analytics tools, one of the key concepts to understand when working with a data warehouse system is the SCD (Slowly Changing Dimension). I will do this in a series of at least two articles. The first one (this one) will be on Read more about SCD: Slowly Changing Dimension, an Ultimate Guide[…]
