I have a spreadsheet that looks like this:


ACCT LAST DISPO BAL Fwd RET DTE ACTION LPY
1234 MOUSE 1234 1111 22 1/25/06 GW 4/6/96
1234 MOUSE 1234 1111 22 2/3/06 GW 4/6/96
1234 MOUSE 1234 1111 22 3/5/06 GW 4/6/96
1345 SMITH 1234 1111 33 5/6/06 GW 5/5/06
1345 SMITH 1234 1111 33 7/16/06 GW 5/5/06

This goes on with different accounts for 10,000 lines. What I am looking to
do is only keep the accounts where the RET DTE is the most recent of however
many may be the same. So what I want to see is this:
ACCT LAST DISPO BAL Fwd RET DTE ACTION LPY
1234 MOUSE 1234 1111 22 3/5/06 GW 4/6/96
1345 SMITH 1234 1111 33 7/16/06 GW 5/5/06

Is it possible to do this?
