I need to add software to Snow, but am not sure of the best way to record this one. We have purchased software which has a perpetual licence, but we have also purchased a SMA for 2 upgrades. The SMA therefore doesn't have a time/date period, but will expire once we have used the second upgrade. I'm very new at Snow, so could be something very obvious, but everything I've tried is asking me to enter a subscription date, when there isn't one. Thanks in advance.
