Hi I don't know if this helps
What I have in my systems is an eventlog table basically contains a datetime, user,table name and memo The memo has entries like: - Contact name changed from "Fred" to "Bill" Phone changed from "0116" to "0117" I've hooked into the tableupdate so that it scans the table being updated and generates the event log record. There isn't much of an overhead as the eventlog table is not keep long and doesn't take too much effort to update. I only use this to find keying errors, but theoretically I could union join different event logs and roll back to any given date. Never had to but its there. Another alternative which I use on newer systems is also to have datetimes for when the record was created and when it was last updated.

That should allow you to see what you have different from another computer's data. -- Michael J.
