Different types of many-to-many relationships in Power BI
The sentence "many-to-many relationships" has different meanings in Power BI. The "classic" many-to-many relationships in a data warehouse is a design pattern requiring a bridge table. A many-to-many cardinality relationship in Power BI is different from the one commonly used in dimensional modeling, and it commonly solves a granularity issue in managing data coming from different data sources. This session clarifies design patterns and best practices for using the different types of many-to-many relationships in a Tabular model for Power BI and Analysis Services.

Column Comparison - Vlookup
I have two columns I need to compare, one column: 'MOM Stocking Report': Shows all stocked items & 'Demand Seg': Shows the complete list of purchased items. I need to compare them against one another to know which ones are stocked and which are not. As you can see the equation below, it appears to get me halfway there as the pie chart does capture the data, however I am not certain this is correct, Also when I click on the 'YES' stocked pie chart, the table shows nothing. Also, technically the 'Agreement Level' should be a 0 if 'Not Stocked' or come back with null. My relationship cardinality is at Many to Many , it wont let me change- I have removed all duplicates from Power Query. So I am basically out of ideas: My Stock or Not Equation: Stocking Agreement? = if(isblank(countx(filter('MOM Stocking Report','MOM Stocking Report'[Item Number]='Demand Seg'[ITEM NUMBER]),'MOM Stocking Report'[Item Number])),"YES","NO")
