One of the key benefits of composite applications is its flexibility, the capability to replace services to accommodate different functional needs. Whether you are upgrading to the newest SAP release, adding new business logic, or integrating new back-end systems — a common requirement in mergers and acquisitions — composite applications enable you to “plug ‘n’ play” different functional implementations by using a common interface. The replacement technique shows you how to replace services without affecting their consumers. Learn how it can help you face the challenges of changing business or IT requirements. Once you have used it, you’ll never let it go.
