If you create a custom cube role to define the dynamic dimension security to restrict the dimension members that are visible to users, and you then specify the top dimension level that can be accessed by the users in the custom cube role, you may receive one of the following error messages when you try to browse a cube by using the custom cube role:
Error message 1
Analysis Server Error: Connection to the server is lost;
Error message 2
Unable to process one or more commands. Unspecified error
This problem occurs when all the following conditions are true:
The Multidimensional Expressions (MDX) expression that evaluates the topmost accessible levelof the dimension uses the IsError function and the UserName function.
An example is an MDX expression that is similar to the following that is used to specify the topmost accessible levelof a dimension:
The user who is trying to browse the cube does not exist in the Users dimension.
After you receive the error message, the custom cube role that you used to define the dynamic dimension security is corrupted. As a result, all the users who belong to the cube role will not be able to access the dimension until the dimension is rebuilt. Also, Analysis Manager may report the following error message:
"Possible data corruption".
