F9 - Cancel

Canceling a transaction reloads the current form or transaction without any further processing. Canceling does not close a form or navigate away from a transaction.

Cancel_Warning

A confirmation dialog is usually presented when any changes have been made since the form or transaction was accessed (or since the last reload/cancel). The dialog (if shown) is usually modal. "Modal" means that it requires a response before the application will allow any further action.
