Tree Rules

Overview

A Tree Rule is a Rule that can be made up of a row and column of one axis. It is used to evaluate data with settings that can be customized. Each row and column can have a specific parameter set for Rule evaluations, and other Rule evaluations can be nested within. 

Example

1. In a Designer Project, click CREATE RULE and click Matrix Rule. Name the Rule and click CREATE.
2. On the Properties panel under the SETTINGS category, click the drop-down list under Rule Type and select Tree [One Axis].
   
   The Tree Rule will delete the top parameter to have the left column as its only parameter. The Output Data column will appear after inserting a new parameter into the Rule Column. Output Data will still be changed to a new type in the Output Data Column. For a Tree Rule to evaluate a string, this string will receive an input of what team an employee is in. The Tree will check if the String is empty. If it is not empty, then the Tree Rule will check if the string matches any of the teams listed in the Rule
