Return sum of accounting dates based upon a match of corresponding cells

[sambusby]

Hi,

I am looking for a formula route to return a count of accounting dates based upon a match of corresponding cells. I’ve had a look through the forum but can’t see a similar answer, although I have seen a few with more complex analysis.

The Reference data is no more than 100 lines. Sadly reference data is locked, and therefore cannot be re-ordered and filtered prior - to allow a range helper.

Any help greatly appreciated.

Looking for multiple criteria formula in place of the red cells (Col F2 down) where it find the search value in the item column (Col A) and list the number of unique corresponding accounting dates (Col C) it finds in the accounting date field.

Thanks
Sam

maybe something like...


=SUM(IF(FREQUENCY(IF($A$2:$A$21=E2,$C$2:$C$21),$C$2:$C$21),1)) Control Shift Enter

try this
