Answer / prasad
this type of problem is clear in datastage8.0.1 version by
using the new surrogate key generator stage.
But whenever we use below 8th version we can will face the
problem in the case of surrogate key.to overcome this
problem use the help of the routines.
we have to pass the maximumvalue of the surrogate key
through the routine.when ever we run the job second time the
routine will pass the max value and it will generate the
sequence from that number only

Answer / kiran
If you want the SCD stage to generate new surrogate keys by
using a key source that you created with a Surrogate Key
Generator stage, you must use the NextSurrogateKey function
to derive the Surrogate Key column.
