Building a Fiori app using HANA Information Models involves several steps. Here is a high-level overview of the process:
Define the data model: The first step is to define the data model that will be used to generate the Fiori app. This involves creating HANA Information Models using the SAP HANA Studio or the SAP Web IDE for HANA.
Create the OData service: Once the data model is defined, the next step is to create an OData service that will expose the data to the Fiori app. This can be done using the SAP Gateway Service Builder or the SAP Web IDE for HANA.
Develop the Fiori app: With the OData service in place, you can start developing the Fiori app using the SAP Web IDE or other development tools. This involves creating the user interface, defining the app's behavior, and integrating the app with the OData service.
Test and deploy the app: After the Fiori app is developed, it should be tested thoroughly to ensure that it works as expected. Once testing is complete, the app can be deployed to the SAP Fiori Launchpad or other SAP platforms.
Overall, building a Fiori app using HANA Information Models requires a solid understanding of SAP HANA and Fiori development concepts. It can be a complex process, but there are many resources available to help you along the way, such as documentation, online communities, and training courses.
