In Microsoft SQL Server 2005 Analysis Services Service Pack 2 (SP2), you create a database role that has the following permissions:
You set the Read Definition database permission for the role.
You set the Read access permission to a cube.
You enable the Enable read-contingent permissions option for the cube.
You specify a Multidimensional Expressions (MDX) expression for the read-contingent permissions.
When you browse the cube under the security context of this role, some values of measures unexpectedly appear as #N/A. However, in SQL Server 2005 Analysis Services Service Pack 1 (SP1), these values are displayed as the values that are derived from these measures.
This problem occurs because of a regression that was introduced in SQL Server 2005 SP2.
