Hi, I am curious. With the XPath expression helper, we have now another kind of syntax produced. But what is the best in terms of performance? [(Status != 'Closed') and (IsActive = true)and ((Start_DateTime <= '[%CurrentDateTime%]') or (End_DateTime<='[%CurrentDateTime%]')) ] or [Status != 'Closed'] [IsActive] [Start_DateTime <= '[%CurrentDateTime%]' or End_DateTime<='[%CurrentDateTime%]'] Thanks for your feedback (and possibly one or the other ways are totally identical at the end regarding the processing time).
