Rule Evaluation Sequence
Rule evaluation follows these steps: 
	 
 
	 - The authorization system sends the transaction to the Scoring Server.
 - The transaction and the score results are passed to the Rule Engine.
 - In the Rule Engine, the UDV calculation rules are executed first.
 - Then the Decision rules for the data feed are executed.
 - After the appropriate data feed rules are evaluated, then the Crossfeed rules are executed.
