In your first post you didn't give all the information.

If your company has an electrical division and has been doing Lutron for many years, there will be someone on staff that should be able to walk you through the programming. It's still a must to go and get proper training too.
You really should work with the exsisting programmer from the very start of a system design through to the end.
During the design stage you will see and learn about all the bits and pieces, the naming of things, and what is being connected to what, and hopefully some why.
Without some understanding of this part, keypad programming would be very difficult.
Good luck, once you get going it becomes pretty easy.
