Prompt-Driven Development: Building Full-Stack SAP CAP Apps from User Stories

[AnuradhaDhingan]

Introduction

• What if you could translate a business requirement into a functional, full-stack application with a single prompt?
• How much faster could you deliver value if the foundational code and project scaffolding were generated for you in seconds?

This is the new reality powered by SAP Build Code and its integrated AI copilot, Joule.

As a turn-key environment on the SAP Business Technology Platform, it unifies the entire development lifecycle, from coding to deployment.

This post demonstrates how to build a full-stack SAP CAP application directly from a user story, showcasing how

generative AI is fundamentally reshaping the developer experience.

Business Requirement

Build an SAP CAP application based on the requirements in the user story below:

User Story

As a contract administrator, I want to create and manage contracts and ‘parties involved’ information in the system,

so that I can effectively track and handle legal agreements and ‘parties involved’ interactions.

Contracts can cover a vast range of agreements, such as sales contracts, service agreements and employment contracts.

Party involved: A ‘party involved’ is an individual, organization, or entity that purchases goods, products, or services from another party,

typically a business or seller.

Common attributes of a contract might include:

1. Contract ID: A unique identifier for the contract.
2. Party involved Identification Number: A unique identification number for the party involved.
3. Contract Type: The type of contract (e.g. sales, service, employment).
4. Start Date: The date on which the contract becomes valid.
5. End Date: The date on which the contract expires (if applicable).
6. Status: The current status of the contract (draft, active, expired, terminated, etc.)

A typical ‘party involved’ has the following attributes:

1. Party involved Identification Number
2. Party involved Name: It refers to the given name of a person or entity, or a label by which they are addressed or identified.
3. Party involved Address: It refers to a physical location where an individual, business, or entity is situated or can be reached.
4. Party involved Contact Information

Acceptance Criteria

Scenario 1: List All Contracts

Given I am logged into the contract management system, when I launch the SAP Fiori application to maintain contracts,

then I should be able to view the list of all the contracts in a list without pressing the GO button.

The list of all the contracts should have : Contract ID, Party involved Identification Number, Contract Type and Start Date. 

The list of filters should include Contract Type, Contract Status and Start Date.

Scenario 2: View Contract Details 

Given I am logged into the contract management system, when I select a specific contract from the list of SAP Fiori application,

then I should be able to view the contract details and parties involved information.
