In enterprise applications, maintaining data consistency and integrity is paramount for reliable business operations. SAP Fiori Elements, a framework for rapidly building SAP Fiori apps based on metadata-driven templates, provides robust mechanisms to ensure data remains consistent and accurate throughout user interactions. This article explores key strategies and best practices for managing data consistency and integrity in SAP Fiori Elements apps.
