Hi All

I have spent may too much trying to figure this out and keep getting stumped and would appreciate any help I can get in getting the RLS working.

My user table, called Query look like the one below but with over 10000 rows.

The Pathd column is defined as PATH(Query[EmployeeID],Query[EmployeeHRContactID])

The UPN2 is an extract of the USERPRINCIPALNAME excluding the domain of the user access the model in the service

The GUIDUPN is a combination of the GUID and the domain.

The PthCntns is TRUE where the incoming USERPRINCIPALName equals the GUIDUPN.

What I need it to display is all the users who report to a user. If the user is Siobhan Jasper (row 14), then I would need to see all the records where Siobhan's EmployeeID appears in the PathD (rows 14 to 22)

The rule on the Role in SSAS is defined as:

=if(
PATHCONTAINS(
'Query'[Pathd],
MAXX(
FILTER(
Query,'Query'[GUIDUPN]=USERPRINCIPALNAME()),
'Query'[EmployeeID])),
'Query'[Display]=1,
'Query'[Display]=0
)

My Gateway will parse the incoming USERPRINCIPALNAME as sjasper001@userdomain.com if Siobhan Jasper is the user viewing the dashboard.

I hope I have explaned this well enough for everyone to understand and hopefully be able to assist me?

Kind Regards

Thanks for this, it works perfectly, as long as SSAS is not involved.

Maybe I should of mentioned that I am running as a direct query model.

Hi @Steve_welman ，

If I didnt misunderstand wrong,you wanna set a RLS with a SSAS model,Right?

Here is a limitation about RLS that is ,only Import and DirectQuery connections are supported. Live connections to Analysis Services are handled in the on-premises model.

Here the link for the reference.
