Answer / ram pothineni
Create a port in Expression t/r and generate a value for
each row using SEQ genrator, then in Agr take count of all
the records. Create 2 condition in router one with SEQ = 1
and another with SEQ = count of rows (this will give last
row). Connect both to target. Dont forget to give reset
option in SEQ generator.
