Hi,

 

I am looking to create a new column that groups my data every n rows. For example I have 1,000 rows, I would like to create a column that assigns the first 100 rows Group 1, the next 100 rows Group 2, and so on until the final row.

 

Does anyone know how to accomplish this?

 

Thanks.

do n=1 to 1000;
output;
end;
run;

data want;
set have;
retain grp 1;
if mod(n,100)=0 then do; output;grp+1;end;
else output;
run;
