I have data
id
1
2
3
Required output is
id id_1
1 6
2 6
3 6
where 6= sum of id's
Interesting idea to sum up ID's.
If you know about SQL, you can use Proc SQL to solve this.
There are for sure other ways using DATA Step programming or using a Proc such as MEANS.
SQL sample:
data have;
infile cards;
input id;
cards;
1
2
3
;
proc sql;
select
id
, (select sum(id) from have) as id_1
from
have
;
quit;

@Sunny4 note that I've modified your subject line to be more descriptive of your question.
Here is one proc+datastep method:
data have; input id; datalines; 1 2 3 ; proc summary data=have; var id; output out=sum (drop=_:) sum=id_1; run; data want; set have; if _n_ eq 1 then set sum; run;

And here's a single data step solution. It's still two passes through the data, but it's a single step.
data want;
set have (in=firstpass)
have (in=secondpass);
if firstpass then sumid+id;
if secondpass;
run;
