I am attempting run a vbs script that should create my cubes, but get the
following error:

-- Error -- BuildDatabaseDimension -- 2/21/2006 10:08:41 AM --
Identifying parameters:
DatabaseName = LMPDB_1000_Dev6_DEV_EN30_MCPosition
ObjectName = BusCube^DateTimes
Error:
-2147221425 - Error occurred during update of Dimension
'BusCube^DateTimes' on the server: 'Level has an invalid MemberKeyColumn'


Does anyone know what might cause this error?
