Once time has been recorded in Invoxy there are a few options for editing and deleting the time.
If the time is Approved, the approval will need to be removed before the time can be edited or deleted, as shown here.
You can then edit/delete the time from the Week Summary screen - click on the Resource's name to view their timesheet.
If the Resource has entered hours you'll be able to see each time entry in the top section of the timesheet view, as shown for Monday to Thursday here:
To edit or delete a time entry, simply click on the entry. In the Edit Time window that pops up you'll have the ability to edit any of the details of the time entry, or click Delete in the bottom left to delete the entry.
Alternatively, you can click the down arrow for the day in the Work Summary at the bottom of the timesheet. This will expand a list of time entries for the day, where you can click into an entry to edit it in the pop up as shown above, or click the x to delete the entry.
