To unapprove a previously-approved timesheet: Note: You can unapprove a timesheet only if you have been given that specific right, enabled by checking the "Allow the user to unapprove a timesheet" box found under "Timesheets Options" toward the end of the Account > User > demographic dialog. Once you have been notified that a timesheet needs to be unapproved: 1. Log in to the Timesheets module, click on the "Timesheets" tab, and then click on the "Approved [Timesheets]" sub-tab. 2. Click on the name of the relevant timesheet, and then on the "Submit/Approve" link. 3. In the "Approval history" dialog, click on the link within the sentences found at the bottom of the history: "You can unapprove this timesheet. Click here to continue." 4. Indicate the reason for unapproving the timesheet in the "Reason" text field in the "Unapprove" dialog, and then click on "Submit." You will return to the "Approval history" dialog. 5. Once a timesheet is unapproved, it will return to "Open" status, where its owner can modify and resubmit it for approval, or delete it if necessary. Please note: Any timesheet whose hours have already been billed to a client cannot be unapproved (and thus cannot be changed). If this is the case, the user may need to create a new timesheet, and the relevant client(s) may need to receive a modified invoice.
