In Informatica how to compare the attribute of previous record with the attribute of the current record.

Example:

From a flat file am getting the records, my reqiurement is to get the duplicate records and load it in one target and to get the distinct records and load it in another target. Please do help me on this....


Thanks & Regards,
Sabarish

You can use the Expression transformation for this.
Assign the incoming value to a variable and then you can check in another variable(or output port) whether the previous variable value is equal to the current incoming value.

Sabarish37,

You can use the below logic
Your mapping flow should be like this

SRC -> SQ ->AGGR -> ROUTER -> TARGET1 and TARGET2

In the aggr put all the columns from source
add a new column ANT
IN AGGR group by the key column
IN the router create two groups
1)CNT =1 TARGET 1 (non duplicate records )
2)CNT >1 TARGET 2 (duplicate records )

Is this answer your question ?
