I was trying to get a list of unreferenced rules in a ruleset . But , only way i could figure out was to use the references from actions menu of a rule. It is painful to open each rule and check for references. Is there any wizard or report which we could execute get a list of unused rules.
Rule references are created when one rule refer other in a model driven way (Property-Set etc. ). They are stored in each rule. If you open XML, you will find a pxRuleReferences page which contains all rules that your rule refers. The internal PRPC table used for this is pr_index_reference.
You can write a Report Definition on this table to get required data.
