Use the Rule Compare utility to compare two different instances of rules, two different rules, or two versions of the same rule. You cannot compare a rule instance with itself, but you can compare two versions of the same rule.
The comparison lets you quickly find the additions, changes, or deletions that have been made between the versions, or between two different rules.
To easily compare two versions of the same rule, use the History tab of a rule form.
To access the Rule Compare utility, click Designer Studio >System > Tools > Refactor Rules > Compare Rules.
