Define A New Variable Value

When defining a metric, instead of setting criteria based on a defined value, you can describe a metric in terms of a variable. At run-time, when an analysis is run, the user is prompted to enter a value for this variable which will subsequently be used in the calculations.

To define a variable value, complete the following steps:

1. Select the Metrics tab.
2. Select the Variables view.
3. In the Variables menu group, click New Variable. Variable x is added to the Variables list.
4. In the Name field, enter a name for the variable.
5. (Optional) In the Value field, enter a value. If no value is specified, you are prompted for it during an analysis. Upon entering this value (at run-time), the variable will store and use this value unless you alter it at a later time.
