Implementation & Getting Started Guide: Your First SAP Fiori App with Business Application Studio

Ready to dive in? Here’s a step-by-step guide to developing your first SAP Fiori application using SAP Business Application Studio. This assumes you have access to an SAP BTP account (trial or enterprise).

Phase 1: Setup Your Development Environment in BAS

1. Access SAP BTP Cockpit: Log in to your SAP BTP Global Account. Navigate to your Subaccount where you want to enable BAS.
2. Enable Business Application Studio:
   • In your Subaccount, go to Instances and Subscriptions.
   • Search for "SAP Business Application Studio" and subscribe to it.
   • Once subscribed, you'll see an application entry. Click "Go to Application" to launch BAS.
3. Create a Dev Space:
   • In BAS, click "Create Dev Space".
   • Give your Dev Space a meaningful name (e.g., "MyFioriDevSpace").

We'll use the Fiori tools application generator for a quick start.

1. Open the Command Palette: In BAS, press Ctrl+Shift+P (Windows/Linux) or Cmd+Shift+P (Mac) to open the Command Palette.
2. Start the Fiori Application Generator: Type "Fiori: Open Application Generator" and select it.
3. Choose Application Type: Select a template, for instance, "SAP Fiori Elements List Report Page" for a quick start, or "SAP Fiori Freestyle Project" for more custom control. Let's pick "List Report Page" for this example.
4. Select Data Source:
   • Connect to an SAP System: If you have access to an S/4HANA or ECC system via a BTP destination, choose "Connect to an SAP System" and select your destination.
   • Use a Local CAP Project: If you're building a full-stack application, you might connect to a local CAP backend.
   • Use a Sample OData Service: For learning purposes, you can use a publicly available sample service (e.g., from ES5 Gateway demo system or Northwind).
   Let's assume you've configured a destination to an S/4HANA system or are using a public sample.
5. Select Main Entity: Choose the OData entity set that will be the primary data source for your list report.
6. Configure View Settings (Fiori Elements Specific): Define the object page details, navigation, and other Fiori Elements specific configurations.
7. Provide Project Details:
   • Module Name: A name for your UI module (e.g., myfioriapp).

   • Alternatively, navigate to the web/ folder (or your UI module folder), open package.json, and look for the "scripts" section. You'll typically find a start script. You can run this from the integrated terminal by typing npm start.
   Your app will open in a new browser tab.
3. Use Fiori Tools Page Editor (for Fiori Elements):
   • If you created a Fiori Elements app, open the Command Palette and type "Fiori: Open Page Map" or "Fiori: Open Page Editor".
   • This visual editor allows you to modify the layout, add fields, and configure annotations without directly editing XML or JSON.
4. Make Customizations (for Freestyle or advanced Fiori Elements):
   • Open the relevant view (.view.xml) or controller (.controller.js) files in your project.
   • Use the code editor, intelligent code assist, and integrated debugger to add custom logic or UI elements.

Phase 4: Deploy Your Application to SAP BTP

1. Build Your Application:
   • Open the integrated terminal (Terminal -> New Terminal).
   • Navigate to your project's root folder.
   • Run npm run build (or mbt build for MTA projects) to create a deployable archive.
2. Deploy to BTP:
   • Open the Command Palette.
   • Type "Fiori: Deploy to SAPUI5 ABAP Repository" (for on-premise ABAP deployment) or "Fiori: Deploy to SAP BTP" (for cloud-foundry deployment to BTP).
   • Follow the prompts to connect to your BTP Cloud Foundry space, select your destination, and deploy.
3. Register in Fiori Launchpad (for BTP deployment):
   • Once deployed to BTP, you'll need to register your app in the SAP Fiori Launchpad service on BTP.
   • In the BTP cockpit, go to Services -> Instances and Subscriptions, find your Fiori Launchpad service instance, and click "Go to Application".
   • Use the Fiori Launchpad Configuration UI to create a new app tile, target mapping, and assign it to a catalog and group.

Congratulations! You've successfully navigated the process of developing and deploying an SAP Fiori app using SAP Business Application Studio.
