DAX Relation between DirectQuery and Import

NathanPzi · ‎05-26-2023

Hello,
I have a report that contains multiple tables, one is in 'Import' mode, and the other is in 'DirectQuery' mode and is linked to another report.
Import: Grille tarifaire[Moyenne]
DirectQuery: Affaire[TJM Vendu]
I'm trying to create a calculated column with this function: Flag TJM PFSA = if(RELATED('Grille tarifaire'[Moyenne]) = BLANK(), 5, if(RELATED('Grille tarifaire'[Moyenne]) >= Affaire[TJM Vendu],1,10))

But Power BI is giving me this error: The column 'Grille tarifaire[Moyenne]' either doesn't exist or doesn't have a relationship with any table available in the current context.

However, I have established a relationship between the two tables using a reference, and the relationship is active with the correct cardinality.
And when creating the column using "RELATED", Grille tarifaire shows up as a suggestion.

If anyone has any tips or a solution to my problem, I would greatly appreciate it.

Thank you 🙂

Hi @NathanPzi ，

Depending on where you create the calculated column; they can have some limitations. If you create a calculated column in an Import table or a calculated table, then there will be no limitation. However, if you create a calculated column in a DirectQuery table, then in the expression for the column only columns from the same table can be used.
