In this video, I’ll break down the key differences with real-life examples, show how they impact data modeling and relationships, and walk you through common issues you may face — like broken relationships, cardinality problems, and duplicate values. 👨‍💻 Whether you're just starting out or building advanced Power BI reports, understanding this concept is crucial for clean data models and accurate DAX calculations. ✅ What you’ll learn: • What are unique values vs distinct values • How to check them in Power Query using column statistics • Why relationships break due to non-unique columns • Real examples from dimension and fact tables • Tips to fix duplicate issues using Power Query and DAX 📂 Dashboard used in this video:    • 2025 Real Estate Power BI Dashboard Tutori...   💻 Visit my GitHub (for DAX formulas, samples, and tools): https://github.com/KosingasBG/PowerBI... 📝 Read more on my blog: https://powerbiwithbogdan.com/ In this video you will learn how to solve following PBI issues: You can’t create a relationship between these two columns because both contain duplicate values This relationship is not a single-direction relationship Many-to-Many relationship warnings Relationships between tables may result in unexpected results Ambiguous relationship paths A circular dependency was detected The cardinality you selected isn’t valid for this relationship. A single value for column ‘ColumnName’ in table ‘TableName’ cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum.
