Many to many relationship - why?
Hi
I don't understand why this becomes a many-to-many relationship? Commission_exeption_table[customer_code] contains no repetitions, but salesInvoices[customer_code] does, I would think it should be a many to one relationship. Both are formatted as text.
Rose__123 The only way that I could replicate this was to have a blank row in Commission_exception. A blank customer_code. Do you have that?

Rose__123 Check casing. M does not consider a and A the same but DAX does.

Greg_Deckler, I double-checked, but it was fast since my Commission_exeption_table only contains two rows. Any other ideas?😅 The only thing I can think of is the blank spaces of the Commission_exeption_table since these also appear (and should appear) in the salesInvoices[customer_code], but can that be?

Rose__123 It's really difficult to say without the ability to see the data. Since it is only two can you make up two that are equivalent to your two ID's? Is the only difference the number of spaces or ?
