Some users are allowed to submit time entries from a timesheet before submitting the entire timesheet.
Submitting entries early gets them approved faster, so your company can bill the client and get paid faster.
When an entry is complete (i.e. you’ve worked the recorded hours, and entered any needed comments), you can submit it.
To submit timesheet entries:
All entries will automatically display with an enabled submit check box beside them.
You can select or deselect every unsubmitted entry in a row by clicking the Select links available by hovering over each column:
Or row total:
The entries will be submitted. Each row that includes submitted entries will become uneditable – including project, task, activity, or billing rate you entered the time against – so that you can’t update these details.
Your timesheet is still open, and will remain so until you submit it (or until it is auto-submitted). You can continue to submit entries, as needed, until that time. Any unsubmitted entries will be automatically submitted when you submit it.
You have to submit the entire timesheet because:
For some users, timesheets automatically submit when they’re due.
You can submit an entry as soon as its complete, and typically submitting earlier is better than later. Talk to your supervisor or project manager if you’re not sure about when to submit entries.
You might be able to, depending on your permissions. If you have access, you'll see a Reopen Row link if you click the 
icon a the end of each row.
And a reopen entry link in the 
bubble for each entry.
Reopening an entry on a submitted timesheet automatically reopens the whole timesheet. However, if you reopen a whole timesheet, individual entries will not automatically reopen.
You can delete entries if they're unsubmitted, or if you have the ability to reopen rows.

displays if you submitted, then later deleted an entry. Resubmission is required to balance accounting for that entry. For example, if 4 hours you worked were exported, then you deleted them, that deletion needs to be recorded.
An icon representing each entry’s approval status displays in each cell: 
for awaiting approval, 
for approved, and 
for rejected.
Plus, the icon, which clicked, shows any comments or validations that apply to the entry, the time entry approver, and a link to the approval history for the item.
A red or orange underline shows entries with validation errors or warnings.
