Fact Table Values Showing Blank When Including Dimension Field
Hi B_Rax ,
I understand what you're saying, and I know it's not an oversight on your part that's causing the table to show up blank with no data in it.
But what I mean is that when it's blank, they don't create a direct connection between them, and in many-to-many it creates a misconnection internally, making the final result incorrect.

Hi B_Rax ,
Since you're using a compound key, ensure that the granularity of your 'Sales' table matches that of the 'Customer Assignments' table. Mismatches in granularity could lead to unexpected blanks in your visuals.

Also I think you can create a DAX measure in your 'Sales' table that handles cases where there is no corresponding 'Outside Salesperson'. This measure can replace blanks with a default value or perform calculations that account for the absence of an outside salesperson.
Profit with Default = IF(ISBLANK(SUM('Sales'[Profit])), 0, SUM('Sales'[Profit]))This measure will replace blank 'Profit' values with 0, ensuring that your visuals do not show blank values unexpectedly.

Thank you for the response. As far as I can tell the granularity is the same between Sales and Customer Assignments. Their relationship works fine as long as the relationship remains 1:* as it breaks when *:*. I created a test Salesperson table which was 1:* with Customer Assignments instead of *:* and that returns expected results. I'm not sure why the *:* relationships with mono-directional filtering do not work even when aggregated as Min/Max.
Regarding the DAX, I attempted to implement it but the default value causes filtered records to appear.
Hi B_Rax ,
Applying many-to-many relationships in Power BI is prone to errors. It's easy to create aggregation or some other unwanted error, so if you can provide me with more information about your problem or .pbix file, I think I can solve the problem more intuitively.

Hi B_Rax ,
I opened your .pbix file and I found that the problem is that in the table Sales when Number is equal to 7412, it has an empty CustomerAssignmentsID, which causes it to not be able to locate the Name when trying to add it in, making it end up as full.
