Impact Policies dialog box
Use the Impact Policies dialog box to add or edit state triggers for contextual or global policies. If a custom state provider is associated with a node, an additional option is displayed in this dialog box.
To prevent sending service events when changes affect a node, check Suppress service events. Choose this option when a service node is used solely to group child nodes.
For a policy or custom state provider, click Add or Edit (not shown) to open the Edit...Policy or Edit Custom...State Provider tab.
