  Dynamically Changing Text Fields in Power BI Using DAX Introduction: In Power BI, dynamic reporting is crucial for providing users with insights that adapt to their selections and filters. One common requirement is to dynamically change text fields based on user selections, such as switching between "Year-to-Date" (YTD) and "Month-to-Date" (MTD) labels depending on the chosen time frame. In this blog post, we'll explore how to achieve this using DAX (Data Analysis Expressions) in Power BI. Solution Overview: We'll create a measure instead of a calculated column in our date table that determines whether it's YTD or MTD based on the user's selections. This approach ensures that the label dynamically updates as users interact with the report. Step-by-Step Guide: 1. Create a Measure: Begin by navigating to your date table in Power BI and creating a new measure. This measure will hold the dynamic label for YTD and MTD. 2. Write the DAX Formula: In t...

  Power BI Realtime scenarios Problem1: You have two tables in Power BI: Table1 and Table2. Table1 contains data with columns IB (Identifier), Date, and EmpID (Employee ID). Table2 contains data with columns EmpID and Date. You want to bring the IB values from Table1 into Table2, matching them based on EmpID and Date. However, you cannot create a direct relationship between the tables, and Table2 contains future dates. You need to copy the IB values to future dates in Table2 based on the latest available data up to each date. Solution: To achieve this, you can create a calculated column in Table2 using Data Analysis Expressions (DAX) in Power BI. This calculated column will look up the latest available IB value for each EmpID and date in Table2, considering only the dates up to and including the current date. Sample Data: Table1 IB Date EmpID SA123 3/1/2023 1 SA231 3/1/2023 1 SA123 4/1/2023 1 SA231 5/1/2023 1 SA345 6/1/2023 1 Table2 EmpID Dat...

Dax calculation Filling Null based on ID column  Real Time Problem: I have a table that has two main columns: Account ID and Customer Name. The Customer Name column contains a lot of blanks but the Account ID field is complete, so I was wondering if there's a way to get PowerBI to recognise that Account ID 1 is used against the Customer Name, and therefore to fill in any blanks as a result of this? I know this is really confusing, here's an example:  Name     AccountID John          1 John          1 Null          1 John          1 So is there a way to get PowerBI to recognise that EmpName = Account ID 1, therefore any rows that have the Account ID 1 should fill any blank cells in the Customer Name column with EmpName?   I want these null cells filled so I can use the Customer Name as a Slicer. Solution: Filled_Name =  IF(     ISBLANK('YourTabl...
