Hi,
I am trying to find dups as follows:

Picid ddate price
1 9/1/2011 40.00
1 9/2/2011 40.00
1 9/3/2011 50.00
1 9/4/2011 50.00
2 9/4/2011 60.00
2 9/6/2011 60.00

So, in the example above, I want row #'s 2, 4 and 6 to be identified as dups as they have the same Picid, and price, but the date changed within the Picid
