DTR is not necessary when the initial posting occurs, so why force sales and operations people to waste time doing it? The accounting supervisor runs DTR at EOD, and gets a pdf with all the transactions on it, instead of scattered across many. If using Sage Alerts, set one up to flag unposted DTR's to run at 9 pm nightly.
My own preference is that non-accounting users shouldn't have to bother with DTR; they certainly see no value in it. So leave that to Accounting.
