Go to the lease card (see image below).
Click the tab called "General" (see image below).
Click the field "Purpose" (see the first image below). When you do so, a list of lease purposes will open (see the second image below). In the list of lease purposes you will see which lease purposes are available in Leases.
Go to the list of lease purposes.
Place your cursor on the lease purpose you wish to rename (see the first image below). When you do so, you will be shown two icons: "Open" and "Delete" (see the second image below).
Click "Open" (see the first image below). When you do so, the lease purpose you are working with will open. When a lease purpose opens, so does its purpose card (see the second image below).
Go to the purpose card.
Click the tab called "General" (see image below).
Rename the lease purpose you are working with by clicking the field "Name" and then entering a new name in the window called "Name" (see image below).
Close the purpose card (see the first image below). When you close the purpose card, you are redirected back to the lease card (see the second image below).
