Process of Returning Multiple Outputs from a Pega Decision Tree Rule

Decision tree Rule:

Decision tree rules illustrate a sequence of tests performed on property values to return an automated decision. Pega Decision rule is also used whenever we want to return a value based on certain conditions. This basically simulates if… then logic and If you're making decisions on series of data that are different from one branch to the next, use decision tree. For example, you can create a decision tree rule to return specific automobile insurance rates on cars manufactured prior to 1990.

For an advanced decision tree complete the Input tab before the Decision tab and for a basic decision tree, complete the Results tab first. To restrict the results to one of a few constant values, complete the Results tab before the Decision tab.
