Parameters

You can replace the constant value of your Expression items with a parameter.

To get started, Specify an expression item parameter.

A parameter doesn't add any new functionality to a filter. Rather, it lets you easily re-use the same filter for certain purposes:

  • To reuse the same filter in multiple Roles that have similar inclusion criteria

  • To use a filter as the Role Member Filter in Role generators

These are currently the only two use cases for parameterized expression items.

A parameter's default value can be a value you specify manually, or it can be a variable. See Variables.

Note

The default parameter value is merely a placeholder during filter configuration, for the sake of previewing the filter results. The default value does not do anything else. When you use a parameterized filter in one of the above use cases, you will always override the default value.
