Each timesheet has a unique timesheet reference number which is used in the historical audit.
Timesheet can be voided if an information on the allocation line is incorrect. However, if a timesheet is completed, with the Completed status, then it should not be voided as a duplicate timesheet and payment may occur. Ensure the business process for correcting the timesheets if they already have been sent do ERP system, such as SAP.
If a timesheet is voided, the hours, extra charges, other costs, and material charges are removed and are available for authorization again. Once a new timesheet is created, a different timesheet reference number is assigned.
