A measure can contain multiple columns combined in an expression. For example, the Profit measure is the difference of two numeric columns: Sales and Cost.
When you build or update a cube in Cube Editor, you can add such a measure.
To add a multiple-column measure to a cube
After adding the measure, you must redesign storage options and aggregations for the cube using the Storage Design Wizard.
You must process the cube before end users can view its data. Depending on the size of the cube, processing may take considerable time.
