Issue with RLS and DAX Measures

Hello everyone, I am facing an issue with a DAX measure in Power BI that uses the ISFILTERED and ISINSCOPE functions. I have implemented row-level security (RLS) based on the email address of the lo...

    MedIDRI - you could use HASONEFILTER ( 'Dim Acteur'[CdVendeur] 

     

     

     

    SWITCH (
    TRUE (),
    HASONEFILTER ( 'Dim Acteur'[CdVendeur] ),
        CALCULATE (
            SUM ( 'Fait Vente'[MesureTCV] ),
            'Dim Acteur'[TypeActeur] IN { "VRC", "VP" },
            NOT (
                LEFT ( 'Dim Acteur'[Code Fonction], 3 )
                    IN { "RDV", "RAV", "DAV", "DC", "DDV", "DAE" }
            )
        ),
    1000001
)

     

     

     

     

     
    I do understand that this will not work if users have access to more than one CdVendeur though. 

     

    Possibilities are this is because ISFILTERED expects a direct filter on the column rather than one from RLS, it's due to the order of the queries (ie. where RLS is applied), it's by design OR we've found a bug with ISFILTERED 

     

    ( marcorusso - do you have any knowledge on why ISFILTERED returns false when filtered through RLS but HASONEFILTER returns true? ) 

     

     

    MedIDRI - ISINSCOPE will not work in this context because with a card 'Dim Acteur'[CdVendeur] is not in the context of the visual. 

     

    I've put a few more things in your file to help explain this. See attached.

Hello MedIDRI 

 

Function Behavior with RLS Use Case
ISFILTERED Operates within RLS Check if a specific column has any filter applied (e.g., slicers, RLS).
ISINSCOPE Operates within RLS Check if a column is part of the grouping or hierarchy context.

 

I reckon working with this filters in the past with RLS and it was working fine for me.
