No. Since the 3700 keeps long-running historical totals, it doesn't work the same as most other systems. Its a true Point Of Sale, meaning everything is recorded at the time it was entered with the current business date, time stamp and employee/cashier shift info. There is no "daily bucket" for totals that can be reopened and you can't back-post transactions. Accountants love that. Seriously. If you're running version 3.0 or higher you can re-open closed checks up to 14 days back, but anything you do will still post to the current business date.
How did your comp checks get closed to cash? Checks that are left open shouldn't automatically close during the EON, they should just carry over into the next business date. You can see this on the top of your Daily System Report in the Checks Carried Over Count and Amount lines. Basically your End Of Night procedure sets a new business date that's used throughout the system, and increments shift numbers for employees and cashiers.
