Exclude Rules
Exclude rules capture incompatible choices that should not be selected together. To create an exclude rule, you indicate the choices that cannot be selected together. During option filtering, selecting one of these choices makes the other choices referenced by the rule unselectable, For example, when specifying features for a laptop using a Sales Configurator, selecting a specific country disables certain laptop configurations that should not be selectable for this region.
