The options for the supersede rules are:
ANY
If you apply this rule to a condition, the condition will supersede all other conditions regardless of the charge, unless the charge is $0, in which case the rule is not applied, and all the other conditions are rated and returned for a total charge for this service.
GE (Greater Than)
Transportation Manager will compare the charge you have specified under Charge ID with the charge for the condition that this rule is applied to, and use the larger one.
LE (Less Than)
Transportation Manager will compare the charge you have specified under Charge ID with the charge for the condition that this rule is applied to, and use the smaller one.
Supersede *ALL
If you want to supersede all conditions rather than just the one specified under Charge ID, you can set up a dummy condition called *ALL. If you then specify *ALL for the Charge ID, and set the supersede rule to ANY for your condition, this condition will always supersede all other conditions.
