How is business logic typically implemented in SAP applications?

Business logic in SAP applications is typically implemented using ABAP code and various business rules frameworks. ABAP (Advanced Business Application Programming) is a high-level programming language created by SAP for developing applications on the SAP platform. It allows developers to write custom code that operates within the SAP environments, enabling complex logic to be executed as part of application processes.

Using business rules frameworks, developers can also manage and implement business rules that define the conditions, criteria, and actions associated with business processes. This separation of business rules from core application code allows for more agile adjustments to business logic without the need for extensive coding changes.

The other options are less relevant to the implementation of business logic. Graphical user interfaces primarily focus on user interaction rather than the underlying logic that processes data. Predefined templates offer structural guidance for configurations or setups but do not encapsulate the dynamic and complex rules of business logic. Lastly, configuring hardware settings pertains to the technical infrastructure and performance optimization rather than the logical processes that dictate how business operations are carried out in an SAP application.
