This Partner Reference Application repository provides you with a “golden path” to becoming a SaaS provider of multi-tenant applications based on the SAP Business Technology Platform (SAP BTP).

The guidance covers building, running, and integrating scalable full-stack cloud applications. It includes an ERP-agnostic design that lets you deliver your application as a side-by-side extension to consumers using any SAP solution, such as SAP S/4HANA Cloud Public Edition, SAP Business One, and SAP Business ByDesign.

By using SAP BTP services and the SAP Cloud Application Programming Model (CAP), your application meets SAP standards for enterprise-class business solutions. It offers a harmonized user experience and seamless integration.

The repository includes the “Poetry Slam Manager” application as a ready-to-run example. It also provides tutorials on how to build the application from scratch using an incremental development approach.

Based on this sample application, you will find the bill of materials and a sizing example. This addresses the question "Which BTP resources do I need to subscribe to and in what quantities?" and serves as a basis for cost calculation.

Imagine you're an event manager, for example, Peter, and your job is to organize and host poetry slams. As your company runs its business on a cloud ERP system provided by SAP, you use its project management component to plan and staff events, to collect costs, and to purchase equipment. Additionally, an SAP partner provided you with a side-by-side application called Poetry Slam Manager (PSM) to publish poetry slam events and to manage bookings of visitors and artists.

The sample showcases how a side-by-side application benefits from using SAP BTP. The qualities relevant for enterprise-grade partner applications, supported by SAP BTP services and programming models.

The application is based on SAP Business Technology Platform (SAP BTP) and SAP ERP solutions. Therefore, here's what you need:

• An SAP BTP account, which includes SAP Business Application Studio as a standardized development environment (a trial account is not sufficient),
• GitHub as your code repository, and
• an SAP ERP system.

The partner reference application targets SAP partners. To learn more about becoming an SAP partner, see the partner program of SAP. However, the tutorials also work for multi-tenant applications of SAP customers.

This repository explains the development journey along the path as shown in the picture:

A complete and working implementation of the above steps is available in separate branches:

1. Core application and multi-tenant deployment: branch main-multi-tenant
2. Additional features (based on the multi-tenant implementation): branch main-multi-tenant-features

This allows you to check out those branches and directly work with the respective implementation. You can use GitHub comparisons to understand the changes required along the development journey.

The tutorials are provided in the (main) branch. If you prefer a quick start with a deployment of the poetry slam manager application including all features without further explanation, follow the quick start guide.

Updates to this repository are documented in the change history.
