Hi I have 2 dataset for example
Table 1
a 1
b 2
c 3
Table 2
a 1
b 1
c 1
a 2
b 2
c 2
a 3
b 3
c 3
how can I seperate non matching records from table-2?
And if you only care about non-matching records, SQL is more handy as it does not require sorting:
proc sql;
create table nm as
select * from t2
except
select * from t1;
quit;

I am not 100% sure about what exactly OP wanted, but here to start the discussion:
data t1;
infile cards;
input id $ a;
cards;
a 1
b 2
c 3
;
data t2;
infile cards;
input id $ a;
cards;
a 1
b 1
c 1
a 2
b 2
c 2
a 3
b 3
c 3
;
proc sort data=t1;
by id a;
run;
proc sort data=t2;
by id a;
run;
data m nm;
merge t1 (in=t1) t2(in=t2);
by id a;
if t1 and t2 then output m;
else if t2 and not t1 then output nm;
run;
'm' will be the records shared by two tables, nm will be the records uniquely exist in table2.
