How to concatenate row data through informatica ?

  

Source:

Ename	EmpNo
stev	100
methew	100
john	101
tom	101

Target:

Ename	EmpNo
Stev methew	100
John tom	101

Approach1: Using Dynamic Lookup on Target table:

If record doen’t exit do insert in target .If it is already exist then get corresponding Ename vale from lookup  and concat in expression with current Ename value then update the target Ename column using update strategy.

Approch2: Using Var port :

Sort the data in sq  based on EmpNo column then Use expression to store previous record information using Var port after that use router to insert a record if it is first time if it is already inserted then update Ename with concat value of prev name and  current name value then update in target.
