Answers were Sorted based on User's Feedback
we can also do it like this
FIRST PIPELINE
From sq connect all the ports to expression t/r and by using sequence generator t/r generate sequence number.
From expression t/r connect the all the ports to the filter t/r write a condition sno=1.
from filter t/r connect all the ports to the target
SECOND PIPELINE
From sq connect all the ports to Aggrigator t/r and dont group by any port,connect the ports to the target
THE DATA FLOW DIAGRAM WILL BE LIKE THIS
sequencegenerator
|
\|/
src--->sq--->expression--->filter--->trg
|
|-->aggrigator--->tgr
I think this will work
