Sumproduct Help?
 

Don't know if it is sumproduct that would do what I want, but from
looking into previous posts this appears like it would be possible?

I have a list of data in columns A:C. What I need to be able to do is
count the number of unique approvers (column C) by the Purchase Order
reference in Column B. I was hoping to do this by a pivot-table but
have struggled as this would only give a true count of occurences and
I've seen similar posts that back this up.

So for the following data-set, I need to show the data as:

Ref: PO Number Unique Approvers
IR2/2008-42059 1230002119 2
IR3565026714-45827 1230002120 1
IR08/29539-43169 1230002121 1

Could anyone possibly help with this should appear as a formula?
Assuming this is to be applied as a 'helper column' principle I could
then use this in a pivot-table.

Thanks in advance. Al.

Assume your data is in the range A2:C6 with no empty cells within the range.

PO = B2:B6
Name = C2:C6

You have the unique PO numbers in the range B10:B12.

Try this array formula** entered in cell C10 and copy down to C12:

=COUNT(1/FREQUENCY(IF(PO=B10,MATCH(Name,Name,0)),ROW(Name)-MIN(ROW(Name))+1))

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER)

Thanks to you both on this. Really appreciate your help. Have just
downloaded the file as well so this will be really useful in pulling
together a pivot-table to show this.

Thanks,Al.
