Specifying a Parameter Range
When you add or edit a parameter, you can specify a range of possible values for the parameter. A range allows you to ensure that the parameter value falls within a specific range of values. Within this range there is a defined minimum and maximum value.
To specify a range for a parameter:
1. Open a configurable module in the Product Structure Explorer, and select the Parameters tab.
2. If you are defining a new parameter, click the new parameter icon . If you are editing an existing parameter, select that parameter in the table and then click the edit parameter icon .
3. From the Edit Parameter window, click the Constraint tab.
4. From the Constraint tab, select Range. The window is refreshed to show a minimum and maximum value.
5. Enter the minimum and maximum values for the range.
6. Click OK.
