Hi,
As expert Ada Lv already mentioned that it works on aggregates so check accordingly. Just additional point, cross-check you don't have any filters as you mentioned for that specific material you are not able to see.
Unfortunately i unable to see the values for that particular material in KF. Have you faced this kind of issue previous.
Does it mean you are able to see for other materials for same key figure but not for one material itself? Or you are not able to see at all?
Regards
Rahul
