Keeping an accurate historical record is important. At times you may wish to “lock” time entries so that they cannot be edited or deleted later. For example, you can lock a set of time entries after you prepare an invoice for those times.

Start by creating a report that contains the set of time entries you would like to lock, and then click the ‘lock entries’ link in the upper right corner of the report menu. All time entries in the current report become locked.

You may also lock individual time slips by clicking on the lock icon to the right of that particular time slip:

Once you lock a time entry, the entry displays a small ‘locked’ icon, and the other controls for editing it become unavailable.

To unlock a locked entry, simply click on the lock icon, and it will switch back to an unlocked icon with the other controls made available again. Only the manager of the project to which the time entry has been billed may unlock a particular entry.
