Filter and SumProduct

J

I am trying to use a SumProduct function but want to be able to do so on a
filtered set of rows. SumProduct is not one of the functions available with
SUBTOTAL. SumProduct is also not available for any of the "D" functions
associated with database calculations.

If anyone knows how to accomplish this I'd greatly appreciate your response.

Thanks!

If, for example, you want to total C2:C9 where A2:A9=jeff and B2:B9=abc, try:

=SUMPRODUCT(--(A2:A9="jeff"),--(B2:B9="abc"),SUBTOTAL(9,OFFSET(C2,ROW(C2:C9)-ROW(C2),0)))

Modify as needed.

JMB,

Thank you for your input; however, my problem is not yet solved (perhaps
because I didn't ask it very well).

You solution works when you know that your are filtering on columns A and B;
however, I was hoping to use this in conjection with a range that is already
filtered using the built in filtering in Excel. In other words, is there a
similar function I could use to calculate the SumProduct of the rows that are
not hidden when a filter is applied to the range of data? Using your formula
I would have to manually change the A2:A9="jeff" and the B2:B9="abc" in order
to apply a different filter to the data.

Your formula is very helpful though, and I will continue working with it to
see if I can play around with it to achieve my desired goal.

Thank you!

I was able to get this working with --(Offset(A2:A9="jeff",0,F1)=1) where F1
is a value representing the column I want to use in my filtering.

Thank you. Still curious about the filtered range issue if that's possible.

I'll add some details, if this does not help, you should supply some example
of your data and what results you are after.

My example assumed the filter range is A2:C9, w/headers in A1:C1 and you
want to sum the visible cells in Column C where col A = jeff and col B = abc.
If col A, B, and C have numeric data and all you want is the sumproduct for
col A, B, and C for visible rows w/o any other criteria, then you can remove
the comparison criteria I added for colA and colB and just use:

=SUMPRODUCT(A2:A9,B2:B9,SUBTOTAL(9,OFFSET(C2,ROW(C2:C9)-ROW(C2),0)))

So if you have the following data w/some rows hidden due to a filter applied
to some other column:

A B C
1 Col1 Col2 Col3
2 0 5 4
3 5 2 1 <hidden>
4 6 1 2
5 4 8 6 <hidden>
6 1 2 2 <hidden>
7 5 3 8
8 12 4 1 <hidden>
9 1 2 3


the Subtotal function returns a 0 for the hidden rows in column C, so the
array looks like:
A B C
1 Col1 Col2 Col3
2 0 5 4
3 5 2 0 <hidden>
4 6 1 2
5 4 8 0 <hidden>
6 1 2 0 <hidden>
7 5 3 8
8 12 4 0 <hidden>
9 1 2 3

Then sumproduct will do what it does and return 138. I only added the
additional constraints for example purposes as that seems to be what most
people ask for - although those constraints could be added via filters on
ColA and ColB instead of built into the formula. If there were certain items
that should always be included or excluded - I would build those constraints
into the formula so I would not have to mess w/those particular filters each
and every time I wanted to work w/ the data.

And, to give credit where it is due, kudos to Laurent Longre from whom I got
the idea (I think - it is in my notebook somewhere).
