SophieAnn asked a question.
Usually in an EA you would create one license with three maintenance periods of one year (or one maintenance period of three years, however).
In case of a Subscription agreement, this will not help, as the number of subscriptions is linked to the licende, not the maintenance periods.
Only option that comes into my mind is to create three subscription licenses for the three years and modify the amount and cost separately.
Unless you have reasons to decide to keep in Snow all expired subscriptions (like if you also use Snow to track the total spent by product/manufacturer over the years), you can simply adjust the license and reduce the number of seats and the start/end date. The advantage is that the assignment is already done.
