How to find the minimum value in a database with multiple values .
I am trying to find the earliest transaction date for a program participant
with multiple records relating to each participant. For example in a list of transactions participants are identified by their SSN, there are many transactions by each participant with the date of each transaction recorded. I want to find the earliest transaction date by each participant without sorting the database. |
One way
=MIN(IF(B3:B300="a",A3:A300)) dates in A3:A300 (need to be real excel dates thus numeric), participants in B3:B300 and the above formula will find the earliest date for participant "a" needs to be entered with ctrl + shift & enter Regards, Peo Sjoblom "billybob1" wrote: I am trying to find the earliest transaction date for a program participant with multiple records relating to each participant.

Assuming the transaction is list in A2:B500, with SSN's in A and dates in B,
and you create a list of the unique participants in D2:D30, in E2 type this formula =MIN(IF($A$2:$A$500=D2,$B$2:$B$500)) You must press CTRL+SHIFT+ENTER to enter this as an array formula. Copy it down through E30.
