If you check the "In Training" box on the POS tab for that employee you should be able to run transactions without anything counting:
Orders will not post to net sales, payments, menu item sales, major/family group sales, etc...
CC's will not actually be authed or included in the batch
Tickets will not print in the kitchen
You can also specify a different check header for training checks if you don't have one already. In the POS Configurator go to Sales/Descriptors/Headers. Create a header, name it "training checks", and enter whatever you want to show up. Then go to Revenue Centers/RVC Print Design/Headers and assign the Training Check header in the Training Header box for each RVC.
As an example, I have a training header in all of our stores that shows the following in wide print across the top of the check.
****************
Training Check
DO NOT PAY

I've done this a bunch of times, but I even after working on the 3700 for 14 years I get nervous about orders being live every time I use it for the first time on a new system. What I always do it ring in a couple of test transactions under a number that's in training:
[ol 1]
[li]One check with real menu items. See how the check prints at the workstation, make sure the orders aren't going to the kitchen & bar, etc...[/li]
[li]One check with something minimal, a cup of coffee or something like $1 open food. Auth and pay it to my own credit card, and then go through the CC batch and settle process. If something doesn't work correctly I'd much rather have a small charge on my card that I can reverse than accidentally charge our guests.[/li]
