Hi experts! I have designed a ROLAP cube with real-time updates option enabled. The cube is correctly processed but now I have a problem when inserting new records on the source database. SQL Server returns me the following error: Server: Msg 8623, Level 16, State 1, Line 1 Internal Query Processor Error: The query processor could not produce a query plan. Contact your primary support provider for more information. I have realized that when designing the storage with very few aggregations (less than 50) the error is not raised and inserts are correctly processed. But I cannot set such a low number of aggregations because the performance is very poor. I am using SQL Server 2000 SP4. SP4 for AS is also installed. I have searched on MSDN but there is not a lot of information about this error. Any idea? Thanks Regards, Jorge.
