I want to relate two tables 'OE' and and 'Salary' with 1:n relationship. 'OE' contains the column with unique Key OE3 and 'Salary' contains the column OE3. If i want to activate the relationshop, there comes the meesage that the 1:n is not possible. What´s the reason?
sorry, you are right, there were duplicates. Problem was there were two values, one without last <Space> one with last <space>. I have found it. Interestingly in Excel and Power BI it is be used as identic value. Only powerquery knows, that therae ar two different values. Now I have deleted the last space, delted duplicates and now I can use 1:n relationship.
Yup, I have encountered this with SQL Server, two values 'Contoso' and 'Contoso ' are considered the same in SQL Server, but Power Query doesn't considers this so it shows both Contoso in the drop down.
DECLARE @test TABLE (Brand VARCHAR(20))
INSERT INTO @test
('Contoso ' ),
SELECT DISTINCT *
