DO we have to use NOOBS while using ID?
I guess you are talking about proc print. I think using a ID statement implies option NOOBS, since the ID variable is supposed to provide observation identification. Compare:
proc sort data=sashelp.class out=class; by sex name; run;
proc print data=class; by sex; run;
proc print data=class; by sex; id sex; run;
proc print data=class noobs; by sex; id sex; run;
You haven't provided enough info regarding your problem.
Please explain your question in more detail.
