If you have been watching Power BI news recently, you know that Power BI fields now support custom formatting. In this short blog article, I am going to explain how to use this feature to achieve your custom formatting. You can do things like showing () for negative values, showing custom date/time formats, and etc. Read more about Custom Format Fields and Measures in Power BI[…]
There are some field properties in Power BI such as formatting, which is obvious to use. However, some configurations on the field level, such as Data Category, is not very well known. Data Category is a configuration that can be helpful in multiple visualizations, In this short article, I’m explaining how to use this option Read more about Using Data Category to Have a Better Visualization in Power BI[…]
In the previous article, I explained how you can build a data model for budget vs. actual, where the grain of the two fact tables is different. The model works perfectly as a star schema. As long as you slice and dice data in the level of granularity that both tables support, then you don’t Read more about Budget vs. Actual Model in Power BI: Calculations and DAX[…]
When I explain the Star Schema and best practices of data modeling in Power BI, Often I get questions such as what if we want to have budget and actuals in the same data model? what if there are two tables with different granularity? We cannot solve it with simple data modeling and relationships, this Read more about Budget vs Actual: Zero Complexity Model in Power BI[…]
You have created a Power BI report with many visualizations and calculations, however, it is slow! And the slowest part of that is the report page with a matrix or table visual in it! Why that visual is so slow? Is this the problem of Visual in Power BI? or Power BI problem at all? Read more about Why my Power BI Matrix or Table Visual is SLOW[…]
Dimensions and Fact tables are the two essential parts of building a data model, and their relationship in the form of Star Schema is the best practice of doing the modeling. However, these are all theories until you really experience it in a real-world example. In this article, I want to put everything you learned Read more about Build Your First Star Schema Model in Action: Power BI Modeling Basics[…]
Now that you know about the dimension and fact tables, it is time to talk about one of the most important concepts of modeling. You might have heard about dimensional modeling or star schema, but you may have vague ideas about what it is, or alternatively, you might have used it, but not sure if Read more about Power BI Basics of Modeling: Star Schema and How to Build it[…]
Fact tables are the core of analysis in a data model. In the previous article, I explained what a dimension table is, and why we cannot have everything in one big table. In this article, you will learn about the fact table, and how it positioned in a data model, you will also learn how Read more about Basics of Modeling in Power BI: Fact Tables[…]
I have written previously about the use cases of Dataflow in Power BI, and one of them was using one Power Query table in multiple Power BI reports. However, I that article just covered the surface, and I still see many solutions duplicating Power Query scripts in multiple files which brings a lot of inconsistency Read more about Move Your Shared Tables to Dataflow; Build a Consistent Table in Power BI[…]
