Unfortunately, there is no option to delete any leave application or timesheet in the system. The only option available is to withdraw the leave application if you do not want to process it.
The appropriate action for handling leave depends on its status: approved or submitted leave entries should remain, while manually added entries under the payroll period can be withdrawn.
Refer to the below links for a better understanding and guidance on how to withdraw leave from the system, including steps for removing manually added leave entries that may block new applications.
