To view employees that have a missing punch that has not been submitted or approved yet, navigate to Team > Time > Reports > Time Allocation > Missing Punches.
Once an employee has submitted a missing punch, that punch will show up in your To-Do Bell in the upper right hand corner of your screen.
Once you have opened the To-Do bell you will see a list of My To Do Items. Submitted punches will be in that list as Timesheet Change Request. View the date and time of the missing punch in the middle of your screen. If you need to, before approving or rejecting a punch, you can open the timesheet to make sure that the punch is correct. The final step is to approve or reject the missing punch.
