Decision Tables -

Records can be created in various ways. You can add a new record to your application or copy an existing one. You can specialize existing rules by creating a copy in a specific ruleset, against a different class or (in some cases) with a set of circumstance definitions. You can copy data instances but they do not support specialization because they are not versioned.

Create a decision table by selecting Decision Table from the Decision category.

Key parts:

A decision table has two key parts:

Field Description
Apply to Select the class to which this decision table applies.

Decision table rules can apply to an embedded page. On the Decision Table 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.

Identifier Choose a unique name that indicates the purpose of the rule. Begin the name with a letter, and use only letters, numbers, and a hyphen.

Rule resolution

When searching for instances of this rule type, the system uses full rule resolution which:

  • 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
  • Finds time-qualified rules that override base rules

In addition, this rule type supports rule redirection.
