Example 4—Limiting Access to a Member and its Descendants

In this example, the database role has access to cells for the Europe member and its descendants (France, Germany, and their City level members) in the Geography dimension, but the role does not have access to cells for any other members in that dimension.

The following expression is the Multidimensional Expressions (MDX) expression that sets these permissions:

Ancestor(Geography.CurrentMember,[Continent]) IS Europe

Reviewing the Result Set

Based on these cell data permissions for this database role, a query on all cells returns the result set shown in the following table.

Important

If a Microsoft Windows user or group belongs to multiple database roles, a query on all cells would first result in a dataset being generated based on each database role to which the user or group belongs. Then, Microsoft SQL Server Analysis Services would combine all these datasets into one dataset, and return that combined dataset to the user or group.
