In order for you to archive a lease, the lease must have the status "Lease".
To archive a lease:
Open a lease. For more information on how to do so, see section 4.6. or 6.1.
Go to the lease card (see image below).
Click the tab called "General" (see image below).
Click the field "Status/archiving" (see the first image below). When you do so, a window called "Status/archiving" will open (see the second image below).
Go to the window called "Status/archiving".
Set an archive date for the lease you are working with by clicking the field "Archive date" and then selecting an archive date in the calendar called "Archive date" (see image below).
Click "Archive" (see the first image below). When you do so, you will be redirected back to the lease card where you will see that the lease you are working with has been, or will be, archived (see the second image below).
