Entities disappear from Report Builder Explorer when datasource is a cube

I have scoured the internet looking for someone who has run into this issue with no such luck!

Product: Reporting Services 2005
Analysis Services 2005

Our users use Report Builder as an ad-hoc report tool. Data sources for Report Builder come from Report Servers and Analysis Servers.

I have run into issues where a user will select a source for their report that is based on an AS cube. When they select an attribute (field) from a selected entity in the Report Builder Explorer and drop it on the canvas, all entities except the one the field was selected from disappear.

For example:

A cube has a fact table called "Annual Income" with dimension of employee and demographics. In Report Builder, the entities would be listed in the left hand Report Builder Explorer window as

Annual Income
Employee
Demographics

If I select attributes from Employee or Annual Income, as usual, you will see the related hierarchies of the remaining entities. However, if I select an attribute from Demographics, then the Annual Income and Employee entities just disappear and all I can see is the Demographics entity and its attributes.

Has anyone run into this and if so, any ideas? This is becoming extremely frustrating. I have deleted and rebuild cubes, individual dimensions, and everything else I can think of.

Your responses are appreciated,
Scott

Anyone?sql
