If you have been using dataflows, and you have the return value of a query as something which is not in the form of a table, such as a record, list, or value. then you have seen that the dataflow automatically converts them all to tables. There is an explanation about it, and a method Read more about Working with Records, Lists, and Values in Power BI Dataflows[…]
I have previously written a blog post about what the ALL function in Power BI is, and how it helps in working with filters in your report. However, still I get many students confused about how to use this function, which parameter to pass to it. This blog post is explaining that in detail. Why Read more about How to Use ALL in a DAX Expression in Power BI[…]
There are a couple of useful actions that help a lot in cleaning data; removing digits, or keeping digits and removing everything else. In this short blog article, I’ll explain a simple method to do that using Power Query.

I have written previously provided an all-in-one script for the date dimension, and also wrote an article about the relative date slicer. However, sometimes you cannot use the relative date slicer (timezone issue can be one example), adding offset columns help to overcome that challenge, and still be able to do flexible relative filtering in Read more about Offset Columns for the Date Table: Flexibility in Relative Date Filtering for Power BI[…]
Working with Power BI and Power Platform dataflows, or using Dynamics in general, might cause you to hear one of these two CDS (Common Data Services), or CDM (Common Data Model). Often there is a misconception about these two, and many people think they are the same. In this article, I’ll explain the difference between Read more about CDS and CDM are Not the Same!

If you are using a date slicer in your Power BI report, a relative date slicer is one of the options to consider for sure. This is a very simple type of slicer to use, but very effective in terms of options that it provides for the user to slice and dice the data. Let’s Read more about Relative Date Slicer in Power BI; Simple, yet Powerful[…]
Recursive functions in Power Query are not very popular, but sometimes very helpful when in need. In this post, I’ll explain what a recursive function is, how it works, and explain it through a famous recursive example of Fibonacci Sequence. Fibonacci Sequence Fibonacci sequence is one of the fundamental recursive operations in math, below are Read more about Fibonacci Sequence: Understanding the Power Query Recursive Function for Power BI[…]
The ability to use Get Data from Folder in Power BI is a very useful option. However, if your sheet names are different in the list of Excel files, then you will face a problem. In this blog article, I’ll explain a method you can use that works regardless of the sheet names.
