Building a Customer Loyalty Program Application with SAP Build Code and Joule Copilot

Introduction

Customer loyalty programs are important for getting customers to come back and making them happy. In this blog, we’ll talk about how to use SAP Build Code and Joule Copilot to create an effective app for customer loyalty programs. Generative AI can help developers cut down on development time a lot while still making sure that everything works smoothly.

What is SAP Build Code?

SAP Build Code serves as a comprehensive development environment, facilitating both program execution and design phases. It has tools for DevOps and application lifecycle management that make it easier to create and add to powerful business apps. Using generative AI tools like Joule Copilot, developers can write code more quickly and connect apps to both SAP and non-SAP systems.

Key Benefits:

  • Side-by-Side Extensions: Maintain a clean core while building extensions.
  • Enhanced Productivity: Use AI-powered tools to optimise development.
  • Interoperability: Build applications compatible with various editions of S/4HANA.
  • Centralised Lobby: Access low-code and classic development tools in one place.

Step-by-Step Guide to Building a Loyalty Program Application

1. Setting Up the Project

  1. Launch SAP Build Lobby: Start by accessing the central entry point for SAP Build products.
  2. Create a New Application: Click on the “Create” button and select “Build an Application.”
  3. Choose SAP Build Code: Opt for the Full-Stack Application option.
  4. Project Initialisation: Enter project details and click “Create.” This may take up to a minute.

2. Creating Data Entities with Joule

Data entities form the backbone of any application. In this case, we need entities for Customers, purchases, and redemptions.

  1. Open Joule Copilot: Launch the Joule assistant within SAP Build Code.
  2. Generate Data Model: Use the following prompt:

Make an app for a customer loyalty program. Set up three types of data: Customers, Purchases, and Redemptions.There must be a field for each customer, which include their name email address, postal address, 7-digit customer number, the total value of purchase and total reward points and the total reward points that have been redeemed. Be sure that every transaction and purchase is linked to a particular customer.

  1. Generate Code: Click “Generate” to create the required entities.
  2. Accept the Code: Review and accept the generated code to reflect updates in the Storyboard.

3. Enhancing Sample Data

Testing requires realistic sample data. Joule can generate meaningful sample data for customers, purchases, and redemptions.

  • Customers:
    • Define customer numbers as 7-digit integers.
    • Ensure purchase values are below 10,000.
    • Use the prompt:

Enhance sample data. Each customer’s total reward points and redeemed points must sum to one-tenth of their total purchase value.

  • Purchases:
    • Assign unique customer IDs to each purchase.
    • Ensure reward points are one-tenth of the purchase value.
    • Use the prompt:

Generate sample data for purchases. Each purchase value should range from 50 to 1,000.

  • Redemptions:
    • Ensure redeemed amounts range from 10 to 100.
    • Use the prompt:

Enhance redemption data. Deduct redeemed points from total reward points.

4. Adding Backend Logic

Backend logic ensures the application functions correctly. Let’s configure logic for purchases and redemptions.

  • Purchases Logic:
    1. Open the Purchases entity in the Graphical Modeler.
    2. Add logic for calculating reward points:

“Reward points equal one-tenth of the purchase value. Update total purchase value and reward points for the related customer.”

  • Redemption Logic:
  • Open the Redemptions entity.
  • Add logic for deducting redeemed points:

Deduct the redemption amount from total reward points and add it to total redeemed points.

5. Integrating External Data

Improve your application with data integration from other systems such as S/4HANA.

  1. Connect to S/4HANA Make use of an already-configured BTP destination to access relevant information about products.
  2. Add an Entity: Import product data into your project using the S4HANA_Joule_Product API.

6. Designing the User Interface

Create a user-friendly application using the List Report Page template, create separate UIs for Customers, Purchases, and Redemptions, and modify the Purchases UI with a product dropdown and auto-calculated fields.

User-Friendly Application Development

  • Use the List Report Page template for UI applications.
  • Create separate UIs for Customers, Purchases, and Redemptions.
  • Modify the Purchases UI with a product dropdown and auto-calculated fields.

7. Previewing the Application

Once you’ve completed the development, preview your app to test its functionality.

Run and Debug: Use the Run and Debug option to start the program.
Check the Features: Evaluate the program’s capacity to generate data, compute reward points, and apply them.

Conclusion

Utilizing SAP Build Code and Joule Copilot It is easy to build a great application for customer loyalty through combining information from different sources, including solid backend logic, and constructing an easy-to-use interface. Begin developing now and explore the potential advantages of customer loyalty programs for your company!
