Shiva is right and he suggested with a great example. You can perform this logic by taking transformer and hashfile stage in server job and if you want to perform scd in parellel then you will have to use change capture and change apply stage.

Yes you can query a hash file using Datastage Administrator --> Command window -->

How would call an external Java function which are not supported by DataStage?
Starting from DS 6.0 we have the ability to call external Java functions using a Java package from Ascential. In this case we can even use the command line to invoke the Java function and write the return values from the Java program (if any) and use that files as a source in DataStage job.
