What is active and passive transformation?

Answer Posted / chandu

Hello All,
I have a query to all of u guys...
U all said If any t/r changes the number of records it is a
active ritee....?

So here my query is about Union t/r, In Informatica by
default Union t/r acts as Union all means allow duplicates..

If I have 2 sources having 20 records each after union t/r
the result should be 40 records so, there is no change in
records, even then it is an active t/r yyyyyyyy?

Is This Answer Correct ?    5 Yes 0 No
