How to: Create and Run an MDX Script
To create and run an MDX Script in Microsoft SQL Server Analysis Services, you need to be in Business Intelligence Development Studio with a cube already created and ready for editing.
To create a Multidimensional Expressions (MDX) script
Open the cube for which you want to create an MDX script, and under View, click Calculations.
If you are not in Script View mode, click the Script View icon.
In the script window, under the CALCULATE command, type an MDX expression. Click the Check Syntax icon and verify that the expression is syntactically correct.
