Building a Fiori app using SAP Cloud Platform Integration (CPI) integration APIs involves several steps, including creating the integration flow in CPI, exposing APIs, and developing the Fiori app. Here's a general outline of the process:
Design Integration Flow in CPI:
Log in to SAP CPI.
Create an integration package and an integration flow.
Define the integration flow to connect to your backend systems, such as SAP S/4HANA or SAP ERP, to fetch or push data.
Configure message mappings, transformations, and any necessary adapters to handle data formats and protocols.
Expose APIs:
Expose the integration flow as an API using SAP API Management.
Define the API endpoints, security policies, and throttling limits as needed.
Publish the API so that it's accessible to external applications like your Fiori app.
Develop Fiori App:
Use SAP Fiori tools in SAP Business Application Studio or SAP Web IDE to develop the Fiori app.
Create a new Fiori project and select the appropriate template (e.g., SAP Fiori Master-Detail Application).
Define the data model for your Fiori app based on the API endpoints exposed by CPI.
Implement UI5 views, controllers, and fragments to consume the CPI APIs and display data in the Fiori app.
Implement any required Fiori features such as navigation, filtering, sorting, and pagination.
Test the Fiori app locally to ensure it's working as expected.
Configure Destination in SAP Business Technology Platform (BTP):
Set up a destination in SAP BTP that points to the exposed API in SAP API Management.
Configure authentication, URL, and other necessary settings in the destination.
Deploy and Run the Fiori App:
Once development and testing are complete, deploy the Fiori app to your SAP BTP account.
Ensure that the destination configuration in SAP BTP is correctly set up to access the CPI APIs.
Launch and run the Fiori app in your SAP BTP environment to verify its functionality.
Monitor and Maintain:
Monitor the performance and usage of both the Fiori app and the integration flow in SAP CPI.
Handle any maintenance tasks, such as updating the Fiori app or modifying the integration flow in response to changing business requirements.
