Decision Tree rules
Completing the New or Save As form

Create a decision tree rule by selecting Decision Tree from the Decision category.

A basic (restricted) rule is created by default; optionally, you can create an advanced rule by selecting Advanced in the Template field. A basic decision tree rule uses only comparisons of property values on the Decision tab. An advanced rule provides unrestricted capabilities on the Decision tab; this copies a template rule. You can alter the effects of this choice later through settings on the Results tab.

A decision tree rule instance has two key parts:

Field	Description
Applies To	Select the name of the class to which this decision tree applies. Decision tree rules can apply to an embedded page. On the Decision Tree rule form, you can use the keywords Top and Parent in property references to navigate to pages above and outside the embedded page. If you use these keywords, include the class and absolute name — or a symbolic name using Top or Parent — on the Pages & Classes tab. C-2560
Decision Tree	Choose a name for this decision tree. Begin the name with a letter and use only letters, digits, and a dash character.

For general information on the New form, see Completing the new rule dialog box. For general information on the Save As form, see How to enter rule keys using Save As.

Rule resolution

TTTT Full rule resolution applies to this rule type. When searching for decision tree rules, the system:

• Filters candidate rules based on a requestor's RuleSet list of RuleSets and versions
• Searches through ancestor classes in the class hierarchy for candidates when no matching rule is found in the starting class
• Finds circumstance-qualified rules that override base rules; supports rule redirection
• Finds time-qualified rules that override base rules
