Hard, Soft or Breakable. This parameter controls what happens when the extension eliminates all available decisions. Hard: All decisions will remain eliminated. Enter a wait state after the logic script has completed. Soft: Roll back any decisions eliminated by this extension. Breakable: Roll back any decisions eliminated by this extension that have a danger point value of True (non zero). The routing modules will first use the danger defined for each individual decision; and, if no danger point has been configured for the decision, then the site-wide danger point will be used. If no danger point can be found for a decision, then the decision remains eliminated. |
