Hi
Below is the code and a note from the log file while executing this code.
Why does SAS think first.usubjid is a varible by itself.
Please advise how to get rid of this note from the log file or an alternate to this code.
230 data mh_fin;
231 set mh mh_test4;
232
233 if first.usubjid then MHSEQ=1;
234 else MHSEQ+1;
235
236 run;
NOTE: Variable first.usubjid is uninitialized.
Thank you
Hi @bharath86,
Have you tried using a by statement with the variable usubjid after the set statement?
Kind regards,
Amir.

Hey,
Thanks for raising that by statement.
I actually revised the code and changed the variable.
data mh_fin;
set mh mh_test4;
by studyid;
if first.studyid then MHSEQ=1;
else MHSEQ+1;
run;
Thank you that helps.
