Hi,

Should you have put the second expression of the Exists() into brackets?

SELECT

[Project Dim].[Project Title].Children on 0

FROM (

SELECT

Exists([Mandant Dim].[Mandant Name].CHILDREN,

{[User Dim].[Username].&[Peter], "User Mandat Fact"}) on 0

FROM [Security Concept])

Second, what about this data

UserDatasourceFact

UserID | SourceID

1 | A

2 | A

"Paul" and "Peter" see same group of projects?

Regards,

Igor
