why do i have such warning message?

[littlestone]

dear all, here is my code:


data test;
input SS;
cards;
123456789
234567891
;
run;

data test;
set test (rename=(SS=ID));
SS=put(ID,$9.);
drop ID;
run;


After running the code, I got following message in the log:


566 SS=put(ID,$9.);
WARNING: Variable ID has already been defined as numeric.
567 drop ID;


The strange thing is: if I change the code:

SS=put(ID,$9.);

to:

SS=put(ID,ssn11.);


There is no any warning message.

Can anyone clarify why is the warning message? Thanks.

Your SAS variable ID is defined as a SAS NUMERIC type variable while you are attempting to use a SAS CHARACTER type format (it has the leading "$" character prefix in the name).

Just as Scott said. Your id is numeric variable and your $9. is character format ,So they are not matched.
So try to
[pre]


data test;
input SS;
cards;
123456789
234567891
;
run;

data test;
set test (rename=(SS=ID));
SS=put(ID,9.);
drop ID;
run;
[pre]
