Hi 

 

I'm looking for code that can keep records who appeared once in my dataset FDFD,  and one appearance for records that repeated more than one time. 

 my code will be for these variables A, B, C, P, PEAKYIELD, and TmDAYS. 

 

Regards

What do you want as output?

 

You're either looking at PROC SORT, which can remove duplicates or unique records as desired.

 

If you're looking to flag the records you need to use BY group processing, this post has an example with multiple by groups.

Please include any code you've tried so far, so we can provide more direction or indicate what you need to change.

I did this code but  this one has deleted records that app

Data  merged;
 set merged;
 by A B C P PEAKYIELD TMDAYS  notsorted;
 if not first.A then A=.;
 if not first.B then B=.;
 if not first.C then C=.;
 if not first.P then P=.;
 if not first.LOGTM then TMDAYS=.;
 if not first.PEAKYIELD then PEAKYIELD=.;
run;

eared only one time
