No matter how much one tries to minimize customization in an SAP system some volume of custom business logic is usually unavoidable. Historically this meant introducing custom ABAP syntax in various user-exists, enhancements, BAdI\’s and custom programs. Given the complex and interdependent nature of an SAP system, it becomes imperative to carefully manage such ABAP-based customization in order to ensure that business logic is in sync across various functional areas and is not duplicated. That\’s where SAP Business Rules Framework Plus (BRFplus) comes into play – a fairly new piece of functionality from SAP that makes it possible to manage all of your custom business logic in a single place and in a re-usable way.
