When you create a parameter for a Requires Dependency that parameter is used to set the parameter value of a target Variant when the Requires Dependency is used.
The parameter cannot be set through the Decision Set Editor or Variant Selector, therefore the Parameter must have a default value or derived value.
The source Variant must not have a parameter defined.
To create a parameter for a requires dependency:
1. Open the Property Pages of the Requires Dependency for which you want to create a parameter.
2. On the Variability Options tab, ensure that the Propagate Parameter Value check box is cleared.
3. Click the Parameter tab.
4. Select the Has Parameter check box.
