Yes, I am referring to the same. It seems like someone has created this Delegation Configuration rule in your application.
And I see that pyValidWhen is Never for the scorecard, It may be because of this you were not able to delegate the scorecard rule. Could you please try changing the when rule for the scorecard Delegation configuration rule and try.
It wasn't "someone". It must've been done as part of the installation process. I'd rather not try to hack it. If it was mistakenly done then I want Pega to tell me its ok to change it. Otherwise I'd like some explanation as to why delegation is not supported. I've been having similar problems getting delegation working for a data type.
