Redirected rule

A redirected rule is a circumstance rule that is configured to reference another circumstance rule for the same base rule. Redirection is available for Decision Tables (Rule-Declare-DecisionTable.

At run time, if rule resolution initially selects a redirected rule, the system accesses the target of the redirection, and that second rule runs. (If the target is not found, the base rule runs.) The system ignores all fields on the redirected rule form, except for the redirection details and the rule name.

Benefits

Redirection can simplify maintenance of a set of circumstance rules. For example, an application might include a decision table named SalesTax that computes state sales taxes for a state and is circumstanced by state code, such as VA for Virginia.

Your application needs one base rule and 50 circumstance-qualified rules, one for each state code. However, if the tax structure of several states (such as Alaska, Delaware, Florida, Montana, and New Hampshire) is identical, you can:

Redirection does not reduce the number of circumstance rules you need to create, but it can reduce your maintenance effort when several of them operate alike (that is, are functionally equivalent).
