Removing duplicates problem

[ambadi007]

I have a data set and it contains Claim sfx and amount , I need to remove the duplicates claim , but the problem here is there could be different sfx in the same claim , if its different for the same claim then I need to keep that claim

Claim     sfx          amount               

100         23           897        

100         23           897        

101         25           789        

101         89           463         Need to keep this Claim because of different sfx

102         56           789        

102         56           789         Need to delete this becase of same sfx

SAS can do this fairly easily:

proc sort data=have nodupkey;

by claim sfx;

run;

However, you should also consider what is the right outcome when CLAIM is the same, SFX is the same, but AMOUNT changes.  perhaps you should go with:

proc sort data=have nodupkey;

by claim sfx amount;

run;

data have;
input Claim     sfx          amount   ;
cards; 
100         23           897        
100         23           897        
101         25           789        
101         89           463     
102         56           789        
102         56           789

proc sql;
create table want as
