take a lookup on t1 and look for dupliates in exp and
collect duplicate values to t2
or
you can hold preveious key value in variable port and can
compare it with new coming value , and you can flag these
rec as duplicate rec if both are matched , i mean previous
and current key, sorter should be used before exp as key
values should be come in sorted order only
(This technique is called forward referencing )
( Note : in other senarios if require you can use self
reference also basing on our requirements )
