Learning to Count Distinct Values with Filters in Power BI Using DAX

Introduction: Counting Distinct Values with Context in Power BI Analyzing data effectively in Power BI often requires calculating metrics that involve specific constraints or filters. One common analytical requirement is determining the number of distinct values within a column, but only after applying a particular filter condition to the underlying data table. While the DISTINCTCOUNT
