I tried adding the "Hostname" as well, the remaining issue is that the Totals are not correct. I have found the issue; The formula for "Diff MOM" does not add a variance per hostname level when drilling down, which means that the Total is incorrect. See attached pictures.
At first I thought it had to do with "Allselected" and changed it to use the "All" formula, but that didnt do it.
I actually did try to add that line to the formula, but it didnt work. Well, except for that the "hostname" is in the table "Detailedvolume". In any case, I get the same result, it leaves the "MOM Diff" blank even though there is a difference, but only on hostname level.
If the formula would calculate on that level as well Im pretty sure the Totals would be fine. Any other suggestions?
Ps. Of course youre right about the "ALL" function, thanks for the explanation, think I was just too tired when I tried that out last week Appreciate the explanation!
