Many of the Customer facing applications had scenarios where Decision tables were called in Data transforms using pxEvaluateDecisionTable/ObtainDecisionTableValue functions. While doing Impact analysis/Deletion/Withdrawing of Decision table rules generally we use Rule reference tool. But Pega clearly mentioned in its Rule Reference component user guide(Present in Market place) and also in some PDN links that they are limiting Rule reference functionality for rules that were determined at runtime. But still if there is possibility for showing these kind of rules would be really helpful especially in large Enterprise applications
