Answer / bsgsr
duplicate records can be eliminated the following ways:
1) by using select distinct option
2) by over riding sql with group by port on the column
which gets duplicate values ( P_key column)
3) by connecting the source to an expression transformation
and flagging the duplicate records to another target by
writing an expression in the exp editor

with out distinct we can do it in 3 possible ways.

3. use rowid, derived table or sub query concept then we can
do this
