how to duplicates from expression transformation without
using sorter before that
Answer / nagaraju bhatraju
1.)
we can distinguish between unique and duplicate records in
informatica by using forward reference technique ,
in the sense , we can store the previous rec key value in
Variable_Port and can be compared with the previous rec key
value , but Data has to be come in sorted order on that key
column , for that we should use sorter transformation.
once if you find the duplicate rec by comparing , you can
flag that rec as dulicate and you can divert it to other
target.
2.) with out using sorter
in order to collect only unique records for flat file ,
just use aggregator before exp transformation, and check
group by on the key column where you are expecting
duplicate records. so you will get only unique records and
duplicate records will be eliminated.
