If required, change the status of the checks in the Check Number Confirmation window:
If you do not want to confirm or void a check, select Unconfirmed.
If you want to void the check, select Void.
To assign the statuses you have selected to the checks in this window, choose Update.
Result
The results depend on the status assigned to the check:
Confirmed checks
These checks are marked as printed and confirmed. They are not displayed in this window again. If you try to reprint a confirmed check, SAP Business One notifies you that the check has been printed before.
Unconfirmed checks
These checks are marked as printed but not as confirmed. They reappear in the Check Number Confirmation window until you confirm or void them. If you try to reprint an unconfirmed check, SAP Business One notifies you that the check has been printed before but that the number has not been confirmed.
Voided checks
These checks are marked as printed and voided. They do not reappear in the Check Number Confirmation window. If you try to reprint a voided check, SAP Business One instructs you to ensure that the printer is loaded with the correct paper.
