Answer / preeti
hi,if I understand this question correctly,lookup itself
eliminate duplicate rows by having options like First
Value,Last Value.So whenever there are more than one row
for matching lookup condition then it gets eliminated by
first value.last Value option.Let me know if I am wrong

hi, preeti,
u r absolutely correct.
the main functionality is to avoid duplicate rows by
selecting first or last value only when the record kming
from the source has multiple matches with the look up cache.

What are the issues you have faced in your project? How did you overcome those issues?
lookup is passive y can't it be active? let us say i have some records in my source like 101,rohit,1000 101,rohit,1000 102,kumar,2000 like wise now as it is having multiple matches i return only first,last value it can't return bouth the values that means lookup is acting as select distinct right by default what means it is active?
