There are tons of articles about advanced tips of Power BI modeling such as advanced DAX, and context transition. However, based on my experience with our clients, I realized there is a big gap in basic content. Hence, this article is going to cover the basic essentials of the relationship. Tips such as: What is Read more about Back to Basics: Power BI Relationship Demystified[…]
Does it take a long time to get your data refreshed in your Power BI model? Should you wait for hours for the refresh to finish because you have complex transformations behind the scene? Does the long refresh time make it hard for you to develop your solution? The good news I have for you Read more about How to Use Dataflow to Make the Refresh of Power BI Solution FASTER![…]
In the first part of this series, you learned how to create an exception reporting for a column in a table using Power Query in Power BI. In the second part, you learned how to initiate that process for all columns in a table. This article continues the section one of creating exception reporting for Read more about Exception Reporting in Power Query and Power BI; Part 2 Catching Error Rows for All Columns in the Table Section 2[…]
Previously, I have written about using Power Query transformations and functions to create an Exception report for Power BI. However, the method I mentioned there, was only doing the exception handling based on one column. In this article, I’m explaining how to do exception reporting for all columns in the entire table. There are a Read more about Exception Reporting in Power Query and Power BI; Part 2 Catching Error Rows for All Columns in the Table Section 1[…]
I have previously written about What dataflow is and scenarios of using it. I also wrote an article about Computed Entity and the important role of that for performance and data lineage. However, a Computed entity is a premium-only feature. There are sometimes that you don’t really need premium functions of Power BI, and only Read more about Workaround for Computed Entity in Power BI Pro: Dataflow in Power BI[…]
I have written about Date Dimension in Power BI in many posts, and it makes sense now to explain one of the most common performance challenges that I see in some of the models. Sometimes, your model size grows significantly big, and you have no idea why!? In this article, I will show you one Read more about Performance Design Tip for Power BI: Be Careful of Dates[…]
In the previous post, you learned about the challenge of security when Implementing it using multiple positions scenario combined with organizational hierarchy. We started to implement the solution using DAX in row level security. This post is the second part of the solution. Prerequisite The sample dataset for this example can be downloaded from here. Read more about Dynamic Row Level Security in Power BI with Organizational Hierarchy and Multiple Positions in Many-to-Many Relationship – Part 2[…]
I have written previously about Dynamic Row Level Security, and some of the patterns of it. Two of the most common patterns that I explained were; Organizational Hierarchy, and Many to Many situations of users and profiles. Recently I came across a couple of questions, which persuaded me to write about another pattern of dynamic Read more about Dynamic Row Level Security in Power BI with Organizational Hierarchy and Multiple Positions in Many-to-Many Relationship – Part 1[…]
The article that I wrote earlier this week about the shared dimension had a lot of interest, and I’m glad it helped many of you. So I thought better to write about the basics of modeling even more. In this article, I will be focusing on a scenario that you have all faced, however, took Read more about Combining Dimension Tables in Power BI using Power Query: Basics and Foundations of Modeling[…]
I have previously written about using Power Query for creating calendar tables, However, some people still love to do that in DAX. There are a couple of DAX functions which makes the process of creating a calendar table very simple and easy; Calendar() and CalendarAuto(). In this short blog post, I’ll explain what are these Read more about Creating Calendar Table in Power BI using DAX Functions[…]
