Correct a Mistake
Introduction
Voiding a Check
You can void a check that was service totalled but not closed by
voiding all items on it. If you are not allowed to void items
entered in a previous round, you can use the [Transaction Void]
key to enter the same items you want to void but with negative
prices. In this way, the items cancel each other out.
Creating a Negative Check
If you need to void a closed check, you can create a negative
check (or negative fast transaction). The negative amount on
the new negative check cancels out the original closed check.
You use [Transaction Void] to do this.
Other Transactions
Cancel a Transaction
You cancel a transaction when you want to end the current
service round without posting anything you did during that
round. The guest check returns to the state it was in before the
current round. If you cancel a transaction in the same round
that you began the check, the entire check is cancelled.
Transaction Cancel is different from Transaction Void.
Return an Item
You return an item that was prepared but was then rejected by
or not delivered to the customer. Because preparation costs are
incurred with returns but not voids, the two are usually tracked
separately.
