I'm facing with irritating part_number changing.
I'm trying to change multipal part_numbers by selecting group of components using ctrl+shift+e (see ORCAD2)
selecting the group which i want to change,
change there part number (to CKG57NX7S2A226M to CKG57NX7S2A226M500JH) and click ok
when i verify this action by clicking properties of one of the components surprisingly it didn't change as i wanted. (attached ORCAD1)
