Hi Harithay,

If you know stage variables can do it and dont know how to write them then do a search on stage variables in the Server forum. There are a lot of examples that have been discussed.

You have the following options:

1. Read. Parallel Job Developer's Guide (parjdev.pdf) provide an excellent resource. Check out Chapter 15 - Transformer.

2. Search. This forum have a long history of information that is very useful for you. Do a search for "stage variables".

3. Train. Ascential/IBM provide excellent training classes to help get you up to speed with DataStage EE. Contact Ascential/IBM for more information.

4. Hire. Hire a DataStage expert to do this job, and/or teach you how to do it.

Your questions are very basic, and have been answered in many different ways. I suggest doing #1 and #2. If both are too much for you, #3 and/or #4 would be your best course of action.
