MDX script in SSAS provides strong functions for multidimensional data analysis, however many problems are hard to solve with MDX actually. Because not all the problems can be cope with MDX script. In other words, these problems will be solved by coding way easily. MDX procedure is supported by all the .NET languages. namespace CustomAnalysisAssembly { public class SPDemo { public static double SalesDifference( double firstVal, double secondVal) { return secondVal – firstVal; } } } The .NET MDX procedure can be used when a assembly that contain the specific procedure is deployed into the
