Hi there,
First time poster and beginner to Power Bi. I have a look up table with a column for a list of companies which I want to create a relationship with a column for companies in a fact table. There were nulls in the look up table which I removed through the Query Editor by filling down into those cells, and then removing duplicates. Within rows of the fact table and its company column there are null values and I cannot seem to create a 1:many relationship. I have also tried to replace the null values with the text 'Blank' to no avail.
I do not fully understanding how Power Bi treats null values. Does anyone know how to manage this?
Here is the screenshot of the relationship window that tells me I cannot have a 1:many relationship.
Solved! Go to Solution.

So, you have find the problem? The blank field is considered as a unique value. If you have multiple blanks in the lookup table, you cannot create One:Many, instead you have Many to Many.

Well it seems that I had a duplicate as I didn't account for case sensitive issues.
