Alert Classification 
Definition
To be able to send different types of alerts under specific conditions, different alert categories are to be defined. A category contains various properties and other specifications that define the alerts within that category, for example expiry date, or the escalation recipient.
Alert categories can be assigned to an alert classification. If you do not want to create a classification on your own, you can always create categories within the default classification folder Unclassified. However, for a better overview, it is recommendable to create different alert classifications to group alert categories that belong to the same topic. For example, you can create the alert classification CRM to group all CRM specific categories such as Contract Cancelled and Decrease in Sales. Alert classifications can have sub classifications which enables you to build up your own classification hierarchy.
Alert classifications are defined in the Alert Management Configuration transaction ALRTCATDEF, see also Defining Alert Classifications.
