Answer / venkatesh

by using aggrigator transformation we can eliminate
duplicate records in informatica
The flow will be like this

source--->aggrigator----->target

in aggrigator group by all ports then the out put is only
unique records
connect it to the target
2)we can do it by sorter also in sorter if we enable select
distinct then it will gives unique row
3)if u r source is database then u can select distinct in
sourcequalifier it self
