Answer / ravindra

A transformation is active does not mean that it always
change number of rows. An active transformation can have
passibility to change the number of rows.

In Source Qualifier we can do SQL-override to limit the
number of rows in whare condition, Sorter can remove the
duplicates when select the property checkbox Distinct, In
Router you can only extract the records from selected
(filtered) group. So the number of rows can be impacted.

Expression is an example for passive transformation. Never
change number of rows.
