ProbTrader: I know I can extract industry fields to excel (through the view editor) and then calculate the custome fields myself but I have to do this for all the names in the stock database and I don't think Excel can handle all that data + the SIPro extraction time can be very long.

Why do you have to do it for all the names in the stock database? I do exactly what you're talking about for subsets of the entire database -- e.g., the S&P 500, or for a larger group, the Russell 2000 --- and both SI Pro and Excel can handle that without any trouble.

In general, I've just found it far easier to not even mess around with the custom fields in SI Pro. Excel has so much more power and the formulae are easier to write, and faster to execute.

So it's really not a workaround, but if I were in your shoes I'd question your presumption that you gotta do them all in one extract. Re-think whatever it is you're doing so you only extract, say, one industry group, or a group of related industries, at any single time.
