Sorry, I apologize. I interjected the question above on entity handling, but failed to note that I wasn't the original poster for this thread. I was curious about the poster's situation because I came across something similar some time ago. Unfortunately, I can't detail the exact circumstances of why I needed to do such a thing. Vaguely, it had something to do with creating a mapping table of some sort. Anyway, the bottom line is that, obviously, I don't know the reasoning WHY behind the original poster's query. Sorry I misspoke. Didn't mean to sidetrack the discussion. Mike Waters
