You are making things too hard
Try this

data select;

 set auditing.recaudit;
  rand=ranuni(8);
run;
proc sort data=select;
  by rand;
run;
data FinalData;
  set select (obs=5000);
run;

Dear SAS users:
Please help me with random generator.  After I ran codes listed below to
randomly pick 5000 records.  I later found that in those 5000 records
consists of duplicates.  Please show me to randomly pick 5000 records
without duplicates.


data select;
do i=1 to 400;
j= (ranuni(0)*total);
set auditing.recaudit point=j nobs=total;
output;
end ;
stop;
run;


Any help is greatly appreciated.

Regards,
