"Hit Policy: Unique" using tblPolicyUnique

According to the Unique Hit Policy, only one rule may be returned. If multiple rules are successful and multiple results are collected, an error will be returned.

This table takes two inputs, age and medHistory and returns two outputs, riskRating and rule.

{decisionTables: {
   "tblPolicyUnique": {
   	 inputs: ["age", "medHistory"], 
   	 outputs: ["riskRating", "rule"],
   	 hitPolicy: "U", 
   	 rules: [
		  [">60,<25", "good", "medium", "r1"], 
		  [">60", "bad", "high", "r2"], 
		  ["[25..60]", "-", "medium", "r3"], 
		  ["<25", "bad", "medium", "r4"]
	   ]
   }
 },
 formulas: {
    "Unique": { formula: "tblPolicyUnique(,,54, 'good')",    finalValue: [] }
 }
}

In this example, given an age of 54 and a "good" medical history, a "medium" risk rating is returned by rule 3.

"Unique": { "value": [ ["medium", "r3"] ] }
