different criteria for dups

podarum — Mon, 28 Nov 2011 03:09:15 GMT

I'm not sure how to title this but here is what I'm looking for.. I have a series of dups but want only the ones that have a USE = Y, BUT if the dups both have USE = N, keep only one (either one).

I tried this but it didn't work :

if ((first.PS = last.PS) and (first.prov NE last.prov)) then first.USE = 'Y';

HAVE:

PS PROV USE

H8G AB Y

H8G AB N

L1T ON Y

M1P ON Y

R8A SK N

R8A MB N

for the R8A keep ONLY one of the 2 even if though USE says N.

WANT:

H8G AB Y

H8G AB N

L1T ON Y

M1P ON Y

R8A SK Y

R8A MB N

Can you post some more HAVE WANT?

Why the red part will be changed from N to Y?

I would like one of the Dupped N's to cange to Y, because the way they were captured in the earlier steps of data manipulation, where even though R8A is in both Prov's, I want one of the them to be counted, I don't want to lose any PS's.

Linlin, that singled out the R8A but it did not change it to USE=Y

proc sort data=have;

by ps use;

run;

data single dup;

by ps use;

if first.use and last.use then output single;

else output dup;

proc sort data= dup nodupkey;

by ps use;

data dup;

set dup;

use='Y';

run;

data want;

set single dup;

run;
