SYMPTOMS

In Microsoft SQL Server 2005 Analysis Services or in Microsoft SQL Server 2008 Analysis Services, you create a mining model by using the Microsoft Decision Tree algorithm. You set the MINIMUM_SUPPORT parameter for the Microsoft Decision Trees algorithm to 9 instead of the default value 10. When you run a Data Mining Extensions (DMX) query on the mining model, you find that extra nodes are generated incorrectly.
