What is Forward Chaining and Backward Chaining and how do you define backward chaining in Rule-Dec-Expression?
how Rule-Dec-Expression will work?
Forward Chaining: You can establish required relationship among properties in a Declare Expression,Constraint, On change and Trigger.When the value of a property is involved in any of the declarative rules, the system checks an internal dependency network for another value that are affected. This is know as Forward Chaining.
BackWard Chaining: Backword chaning exectives declartive expression rules when a value is need for a property rather than when inputs changes.Backword chaning applies to Declartive expression in the Change Tracking tab of calculate value field set to one of the following situations
—>When used, if no value present
—>When used, if Property is missing
