Power BI has some built-in, easy-to-use DAX functions to get the Day of Month and Day of the week, but nothing for Day of Year and Day of the quarter. These calculations, however, are very simple and easy to implement using other functions. This short blog and video explain a method to calculate those for Read more about Day of Year and Day of Quarter – DAX calculations for Power BI[…]
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[…]

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[…]
