Filtering DAX RLS

[Anonymous]

Hi Everyone,

Would you please tell me what might be wrong in the following DAX RLS expression?

( [EMC EMAIL] || [DELL EMAIL] ) = userprincipalname()

I have two email columns, one @dell.com and the other @emc.com ... so whether username at dell or at emc to filter this column.

Please help 

thanks,

Amr

Hi @Anonymous ,

When using your RLS expression, it will produce the following error message:

As the error message mentioned, ( [EMC EMAIL] || [DELL EMAIL] )  is a true / false expreesion while userprincipalname() is a text expression, they cannot be compared with each other.

The right expression should be like @blopez11  mentioned:

[DELL EMAIL] = userprincipalname() || [EMC EMAIL] = userprincipalname()

It will work when checking the RLS role.

Maybe try:

( [EMC EMAIL] = userprincipalname () || [DELL EMAIL] = userprincipalname() )
