OLAP Cube fails if I add enterprise resources using SQL Server 200

[Liamo]

I have instaled Project Server 2003 with SQL Server 2005. I have applied the
MS hot fix 921115. I can get the OLAP cube to build as long as there are no
resources in the Enterprise Resource Pool but as soon as I add a resource the
OLAP cube build fails with error: The cube scheduled to be built on
03/10/2006 at 21:00 failed.

(-2146233088) Errors in the OLAP storage engine: The attribute key cannot be
found: Table: MSP_CUBE_RES_AVAIL_FACT, Column: RES_ENTRUID, Value: 5. Errors
in the OLAP storage engine: The process operation ended because the number of
errors encountered duri

Any help appreciated!
