Some STEP implementations have a large number of business rules in place, some of which are executed as part of an approval process (determined by the On Approve setting on the rule itself). The Business Rule Approve Overview section of the System Settings editor serves to consolidate all rules executed with approvals so that they can be easily identified. The name listed under the business rule column is a hyperlink to the business rule so that a user can quickly access and edit the business rule.
For more information about approval-based business rules, refer to the Business Rules on Approval section of the Business Rules documentation here.
