System Testing : This is the iterative process. The focus
is to to get the correct answer or effective answer.This is
done after the Unit test is carried out.
Some cross module errors could also be resolved at this
stage. Post analysis the necessary corrections to the
components are made and finaaly the modules are successfull
system tested when the errors are non-existent or
negligible.
Integration Testing : This is the final stage as all the
errors are removed almost and is at the final stage, so
here we concentrate on integrateing the results across
modules. performance of the etl is tested.
Any new answers are pls provide

Answer / gagan
We can use expression transformation and in expression
transformation we can compare previous records and current
records and if previous record matches the current record
then we can keep a value as 'Reject' for a variable port
and otherwise null.
After that by applying filter tansformation we can remove
all records which have column value as 'Reject'
This will remove duplicate values.
