Hi,
I have an input file:
Input:

Code:

A        B C    D
----------------------
C1111 A P11 080711
C1111 A P11 080711
C1111 A P11 070711
C1111 A P11 070711
C1111 A P22 080511
C1111 A P22 080511
C1111 B P11 080711
C1111 B P11 080711
C1111 B P11 060711
C1111 B P11 060711
C1111 B P22 060711
C1111 B P22 060711


Output should like:
Code:

A        B C    D
----------------------
C1111 A P11 080711
C1111 A P11 080711
C1111 A P22 080511
C1111 A P22 080511
C1111 B P11 080711
C1111 B P11 080711
C1111 B P22 060711
C1111 B P22 060711


The requirement is for all records having Col A, B and C matching; check Col D. , and out records having greatest value of Col D.

Now if Col A and Col B are matching and Col C is different no need to check Col D.

Thanks.

Thanks for the response.
There is a bit of modification in the requirement.
Input file:
X C1111 A P11 080711 Y
Y C1111 A P11 080711 X
X C1111 A P11 070711 X
Y C1111 A P11 070711 Y
Z C1111 A P22 080511 Z
S C1111 A P22 080511 S
AZ C1111 B P11 080711 AZ
ZA C1111 B P11 080711 ZA
AZ C1111 B P11 060711 AZ
ZA C1111 B P11 060711 ZA
A C1111 B P22 060711 A
B C1111 B P22 060711 B

Output file should like:
X C1111 A P11 080711 Y
Y C1111 A P11 080711 X
Z C1111 A P22 080511 Z
S C1111 A P22 080511 S
AZ C1111 B P11 080711 AZ
ZA C1111 B P11 080711 ZA
A C1111 B P22 060711 A
B C1111 B P22 060711 B

i.e if Col A, B and C matching; check Col D. , and out records having greatest value of Col D.
So all other values of the record being selected should be from the records having greatest value of Col D.

With your solution I am getting output as:
Y C1111 A P11 080711 Y
Y C1111 A P11 080711 Y
S C1111 A P22 080511 S
S C1111 A P22 080511 S
ZA C1111 B P11 080711 ZA
ZA C1111 B P11 080711 ZA
B C1111 B P22 060711 B
B C1111 B P22 060711 B

Please let me know if you have a solution to above requirement.
Thanks
