I believe that reason is that it checks for DECONS="Ontime from ETA" and
SPLIT="E"

then

DECONS="Ontime" and SPLIT="W"

In other words the first item in DECONS and the first item in the SPLIT
array then the 2nd item in DECONS and the 2nd item in the SPLIT array. NOT
the first item in the DECONS array with both items in the SPLIT array.

Can anyone help me to understand why this formula gives the correct
result:
=(SUMPRODUCT((Region="Asia")*(DECONS="Ontime")*(SP LIT={"E","W"}))
+SUMPRODUCT((Region="Asia")*(DECONS="Ontime from
ETA")*(SPLIT={"E","W"})))

But if I try to condense it further to:
=SUMPRODUCT((Region="Asia")*(DECONS={"Ontime from
ETA","Ontime"})*(SPLIT={"E","W"}))

It stops working?

Seems to me that, if it can manage to look for either "E" or "W" in a
single SUMPRODUCT, why can't it also look for "Ontime" or "Ontime from
ETA" in the same SUMPRODUCT?

Can SUMPRODUCT only handle one of these per array?

Thanks much,
