If source is relational then select data through query with distinct.
If source is Flat file then in mapping use Sorter and Aggregator Transformation with group by option.

How to transform rows into column using Normalizer in Informatica?

+1 vote

I have developed an Informatica PowerDesigner 9.1 ETL Job which uses lookup and an update transform to detect if the target table has the the incoming rows from the source or not. I have set for the Update transform a condition

IIF(ISNULL(target_table_surrogate_id), DD_INSERT, DD_REJECT)

Now, when the incoming row is already in the target table, the row is rejected. Informatica writes these rejected rows into a .bad file. How to prevent this? Is there a way to determine that the rejected rows are not written into a .bad file? Or should I use e.g. a router insted of an update transform to determine if the row is insert row an then discard the other rows?
