The Lease tab is only available if the asset has been included on a lease. This tab is available for Fixed, Equipment, Property, and Software assets.
The tab shows information about the lease that the asset is attached to, including the lease ID, status, and the lease term information.
If the asset is attached to a lease with an instalment type of Asset Based, you can also see the instalment amount for the individual asset, and what percentage the asset instalment amount is for the total lease instalment.
