Hi,
I wanted to try new Dax function INDEX. But I received an error. What could be the reason ?
Data;
I wanted to create a new table with one row which includes highest profit. But "Relation parameter may have duplicate rows." error occured.
Thanks a lot in advance.
Hi @kivancc94
The syntax for writing DISTINCT (Column) Function:
DISTINCT(<column>)
Where,
Column- It is a column from which unique values are to be returned.
Ex. DISTINCT([ProductPrice])
It returns the unique values from the column ‘Prod uctPrice’.
If this resolve the problem please give a like and make the question as resolve
Thanks and Regards
