Hi Tejaswini, 

Let me explain you clearly about Rule availability,

Not Available: This is specific to Particular ruleset version.

      Eg: If a rule name XYZ is in 01-01-05 and 01-01-04, when you set 01-01-05 to "Not Available" then during run time 01-01-04 will be picked for execution.

   
Available : rule with highest version is picked during run time.

      Eg: If a rule name XYZ is in 01-01-05 and 01-01-04, so during runtime runtime 01-01-04 gets picked.           

Blocked : This Blocks all the rules with same name irrespective of any ruleset in the application

      Eg: Consider you have rule XYZ in ABC:01-01-02 and EDF:01-01-02

            if you make XYZ rule in ABC:01-01-02 as Blocked then the rule in EDF:01-01-02 will also be not picked during run time.

        
Withdrawn:This block all the rules lower the version of the withdrawn rule.

     Eg:  Consider you have rule XYZ in ABC:01-01-02,01-01-03,01-01-04

             if you make 01-01-04 withdrawn, the rule is never picked of any ruleset version.

             if you make 01-01-03 withdrawn, then the rule in 01-01-04 get picked during run time.

          
Final: We can't change this rule until and unless we save it into another ruleset.

     

As per provided Image,

RulesetC:01-17-99 is withdrawn but the higher version 01-09-12 is available so the rule is picked during run time.

I Hope you understand and let me know if any queries.

Thanks,

Bhanu Prakash.
