Transformationi kettle

Hi gus,

I am new to Pentaho DI(Kettle). I stuckup o one issue in transformatio. Please see the details below.

I am using Stream Lokup to do the matching of 2 csv files.But in the output parameters, the field obtained in the stream lookup field is null, instead of the actual value it should return.

Kettle version I am using is : Kettle 5.0.1

Could somebody know why it is so?

Thanks,
Arun
