Rho allows you to revoke a bill that is already scheduled to be paid. Once a bill is revoked it is given a status of Not Acknowledged. Bills with this status can be Acknowledged from the Bill Details page.
To revoke a bill you must access the Payment page by clicking the Accounts Payable icon from the Rho Toolbar. Then, click on the 3 dots button of the bill you would like to revoke as shown in the image below.
The bill is removed from the Scheduled table and can only be accessed from the Bills page. For more information, see Understanding the Bills page.
