Hi Krishna,
i think you r wrong...he is asking abt flat file...
by using LOOKUP we can eliminate duplicates...
You can eliminate duplicates and can capture that duplicates
using
dynamic lookup cache. look up the target table if New lookup
row=0 then it is unchanged (duplicate
record) SEND TO ONE TARGET

here i m taking the example of employee table
first use the sorter to get the distinct value....
then use the agg trns, create the output port and use the
count function on employee_id to get the total no. of rows
like.. count(employee_id) and group by employee_id.
create filter trns.. write a condition where output>1... map
it with the target...
