What You Need to Know About Developing Fiori Applications

Fiori applications have gained great momentum lately, thanks to their responsive design and customizable nature. Large companies, in particular, are transitioning towards using Fiori together with Hana. But Fiori’s standard applications aren’t exactly one-size-fits-all and many companies’ needs can only be met with customized Fiori applications that need to be developed. It is worth noting, however, that doing so with the standard Fiori development methods may require a great deal of effort, resources and cost. That is why the methods through which Fiori applications are developed in line with a client’s needs must be thoroughly analyzed. In this blog post, I will briefly discuss development methods, their advantages and their disadvantages.

Development Methods

SAP Fiori Elements

SAP Fiori Elements allow making use of standard application features and templates, enabling users to develop Fiori applications in less time and at a lower cost. With this method, the SAPUI5 code is automatically generated in accordance with the defined Metadata and Annotations on CDS. The fact that Odata services are also generated from CDS significantly reduces cost and development time for applications. Fiori Elements also enable features such as saving variants, filtering, grouping and sorting by default. Furthermore, Fiori Elements support mobile devices without the need for additional development. CDS views support Create, Remove, Update, Delete (CRUD) actions through the Business Objects Processing Framework (BOPF); meaning these features are also available with SAP Fiori Elements. This structure allows developing Fiori applications that can generate reports, make analysis, create documents and carry out updates.
