How to avoid Duplicate Rows in Informatica

Duplicate Rows in informatica can be avoided by selecting the distinct Check box in the Source Qualifier Transformation.

If  the Source is a Flatfile then it cannot be Prevented by Source Qualifier to give Distinct Data.
For avoiding the duplicate rows we have to use a transformation called Sorter transformation and Select the option called as "Distinct".

One more option to avoid the duplicate rows is by using an aggregator transformation . A groupby in any one of the duplicate column will provide us a result of non duplicate records. 


  1. Its always better to avoid duplicate by using the Source Qualifier tf., If your Source is not a flatfile:)

  2. Really nice.. Thanks..
