Some SAP ASE applications are offered as base products with optional features that require a separate license.
Customers can mix license types. For example, customers can order SAP ASE under the Server License (SR) license type and order an optional feature (for example, High Availability or Enhanced Full Text Search) under the CPU License (CP) type.
Optional features are licensed only with the base product of the same product edition. For example, if you order SAP ASE, you cannot use a Small Business Edition optional feature license with the Enterprise Edition base product. In addition, the entitled use of the license types must be compatible; for example, both types should allow use in a production environment.
