Formula needed to look through accts and flag acct with most recent date

**khauskins** · 05-17-2013, 05:31 PM

Hello,

I need to look through a list of account numbers and dates and determine which row has the most recent date for that account number. For example, I would need to flag the first and third rows with a '1' because the date associated with that record is the most recent, while rows 2 and 4 would need to be marked with a '0'.

Acct # Date Most Recent
12345 5/17/2013 1
12345 5/15/2013 0
54321 5/4/2013 1
54321 5/1/2013 0

So I need a formula that can look through a non-unique list of values and return a '1' for the value that contains the most recent date.
Does this make sense?
Thanks in advance!!

Hi khauskins,

If 'Acct #' is in column A and 'Date Most Recent' is in column B, then in C2, try this array-formula... =IF(MAX(($A$2:$A$5=A2)*$B$2:$B$5)=B2,1,0)

But instead of just ENTER, you have to use array-enter (CTRL-SHIFT-ENTER)... magical curly brackets will appear... copy this formula to the rest of the cells in column C...

Let me know if you have any questions...
