Sometimes when you apply the dynamic row-level security, you want to have the criteria as NOT EQUAL and NOT IN. This can be a bit tricky in the dynamic implementation of RLS, because the relationship behavior is normally the opposite. In this article I’ll explain how you can do that. Introduction I have written many Read more about Dynamic Row-Level Security in Power BI with NOT IN or NOT EQUAL Rule[…]
If you have a visual in the Power BI, that based on some selections of a slicer it might return nothing, depends on the visual, you might get a blank visual, or some other types of improper view. In this blog, I share a simple trick that you can use to have an alternate message Read more about Showing an alternate text when no data available in a Power BI chart visuals[…]

Did it happen to you that you have calculated a cumulative total (such as running total, or year to date, etc) either using the quick measures or by writing the DAX expression yourself, and then realizing that the calculation happens even for the periods without any real data? For example, you want to stop that Read more about Stop DAX Cumulative Total Calculation in Power BI[…]
Despite my many articles about the importance of star-schema and design principals of fact and dimension tables. I still get this question a lot: “When is good to combine tables vs loading them in the Power BI and creating a relationship between them?” This article is going to answer this question.

If you even need to show your DAX measures in a chart without a dimension to slice and dice it, you won’t get a great experience in the visual. In this blog post, I’ll share a trick that you can use to have a nice visualization like what you see in the above screenshot. How Read more about DAX Measure in the Axis of the Power BI Report[…]
I often get this question: “Is it better that I create this calculation as a snapshot table in Power Query (or T-SQL, or the data source), or write DAX measures for it?” If you ever had a scenario of creating a report of snapshots, you know what I mean. “Should I have a table for Read more about Power BI Modeling Tip: Snapshot Table, or DAX Measures?[…]
I have previously explained how to generate a row-number using Power Query. That method is good for pre-calculating row-numbers in the table. However, sometimes, you want to calculate the row number in a visual, based on something dynamic. That is where DAX comes handy. Let’s see how this is possible. Sample model I have a Read more about Generating Row Number in Power BI Visualization Using DAX[…]
I often get this question after I explain about the star-schema. The question is that both my dimensions are filtering my fact table values, but how can I get one dimension filtering another dimension? for example, how can I get only the list of products that have been purchased by this customer?
