Hi all, I am trying to do the practice on Dashboard/ My courses/ SAS Programming 1: Essentials/ Lessons/ Lesson 3: Exploring and Validating Data. The code I wrote is: proc sort data=PG1.np_largeparks nodupkey out=park_clean dupout=park_dups; by _all_; run; and the code solution says: proc sort data=pg1.np_largeparks
out=park_clean
dupout=park_dups
nodupkey;
by _all_;
run; Unfortunately, neither of them works. I pasted the log below. Cant figure why there appears 0 observations. The solution says there must be 30 duplicates. Thanks, Cagri
