Thank you soo much Alan for your help.

It's works !!
But i still need something . I've make the rule in my prolog tab like this which is make the new view. But i didn't need the new view. I don't understand how to remake my formula to copy element value without make the new view . Note : P0 is the source element and P1 is the element that i want to put the value

SUBSETDESTROY ('Scenario', 'Emptysubset2');
ENDIF;
