Hi, Kashan:
Can you clarify which SAS Academy module you are working in? Also, the course you are working in (Chapter/Lesson & Section)? Which exercise or demo or case study you're doing? That will help me narrow down the subject matter experts who can review your question. You could be asking about Enterprise Miner, but you could also be working in a different course, with different software.
Thanks, in advance,
Cynthia
