Draft entries are entries where a mandatory* field is missing, but that still get saved on your timesheet for you to fill out that information once it is available for you.
The draft entries will be always on top of your confirmed entries and with a blue design to differentiate them from the confirmed entries, which are green.
You can go back anytime to your draft entries, click on them, fill the information that are missing, save them, and they will become a normal confirmed entry.
*Please, note that the requirements for draft entries and for confirmed entries may vary for one account to another. Some accounts might not work with draft entries. Please, reach out to firstname.lastname@example.org to know more or to request a change on your account's configuration.
