Calculated Measures
Process
To create a Calculated Measure within the Jet Data Manager open your OLAP Server in the Solutions Explorer and expand the 'Cubes' tree. Once there expand the cube that you would like to create a Calculated Measure for and then rightclick on 'Measures'. This will present you with a menu in which you'll select 'Add Calculated Measure'.
A new window with the following selections will appear:
 In the Name field, type a name for the calculated measure.
 In the Associated Measure Group dropdown select the measure group that your calculated measure will appear under
 In the Format string field, specify how you want the numeric results displayed.
 Check the Visible box if you want the value to be displayed in the frontend application.
 In the Nonempty behavior list, select the measure or measures used to resolve NONEMPTY queries in MDX. This is optional and left blank by default.

In the
Expression
field, write an MDX statement or, in the
Measures
list, drag the measures to be used for the calculated measure into the work space in the middle.
 Drag and drop any relevant item from the list on the right hand side into the Expression field.
 All mathematical symbols are allowed to create your calculation.
 Your expression should only contain the definition of your MDX query.
 In general, this will be everything following your initial 'AS' statement yet before your 'SELECT' statement.
