A tier discount rule determines how the tier model applies to the rates in the rate plan.
If you do not want to use all the tiers set by the tier model, the tier discount rule allows you set the lowest tier applying to the rate plan.
You also set the exact discount percentage that applies to each tier. The values you can declare are limited by the minimum and the maximum boundaries set for each tier in the tier definition rule.
For more information, see How to Set Tier Definition Rules .
You can only set the tier discount rule if a tier model has been defined for the property.
