SYMPTOMS

When one or more dimensions in your Microsoft SQL Server 2000 Analysis Services cube support ragged hierarchies and then you try to create a cube role to define custom dimension security to restrict the members of the ragged dimension that are visible to users, you may not be able to create the cube role successfully.

This problem occurs when all the following conditions are true:
  • You create a custom rule for dimension security by selecting the dimension members from the dimension member tree under the Members section in the Basic tab of the Custom Dimension Security : DimensionName dialog box.
  • The dimension members that you select are the ragged dimension members that have hidden parent members.
You may notice that the Multidimensional Expressions (MDX) expressions that are automatically generated in the Allowed Members box and the Denied Members box in the Advanced tab of the Custom Dimension Security : DimensionName dialog box are not correct.

Additionally, you may receive the following error message:
Unable to update role in cube CubeName.

Error occurred during update of Cube CubeName on the server: 'Error occurred while processing security for cube 'CubeName' (Error in the definition of the dimension security for the dimension 'DimensionName' and role 'CubeRoleName'. Cannot evaluate the expression MDXExpression
Note In this error message, CubeName is a placeholder for the name of your Analysis Services cube, DimensionName is a placeholder for the name of your Analysis Services ragged dimension, CubeRoleName is a placeholder for the name of the cube role that you are trying to create with custom dimension security, and MDXExpression is a placeholder for the incorrect MDX expression that is generated in the Custom Dimension Security : DimensionName dialog box.

CAUSE

To retrieve the dimension members and to display the dimension member tree in the Members box, the Custom Dimension Security dialog box connects to the Analysis Manager with the MDX Compatibility connection property set to 2. Therefore, hidden dimension members are not displayed in the dimension member tree. Because the MDX Compatibility connection property also affects the unique representation of the dimension member names, the format that is used by the Custom Dimension Security dialog box to generate the dimension member names is different from the format that is used by the Analysis Services server. Therefore, Analysis Services server cannot evaluate the custom dimension security definition successfully and you receive the error message that is mentioned in the "Symptoms" section.

RESOLUTION

Prerequisites

This hotfix requires Microsoft SQL Server 2000 Analysis Services Service Pack 3 (SP3).

Restart information

You do not have to restart your computer after you apply this hotfix.

Registry information

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

After you apply this hotfix, a new String registry value Show Hidden Members in Dimension Security is created in the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\OLAP Server\Olap Manager Info

The Show Hidden Members in Dimension Security registry value helps the Analysis Manager control the values of the MDX Compatibility connection property and the Member Names Unique dimension member property.

You can use the following values for the Show Hidden Members in Dimension Security registry value:
  • True
  • False
Note After you change the registry settings, you must close and then reopen the Custom Dimension Security dialog box for the change in the registry settings to take effect.
