Hiya, Why would you want to? Any time you need days elapsed, just compute it. Never store summary data without a good reason. (making things go faster is a good reason) :)

I already have some fields called order number, orderdate, and shipdate. I am trying to create a new field called dayselapsed and have it subtract the order date from the ship date. It would need to look like this: Ordernumber Orderdate Shipdate DaysElapsed 1 1999-07-01 1999-07-03 2 2 1999-07-01 1999-07-04 3 I have no idea how to do this. Could someone include the exact commands, as I am lost? Thanks!
