Welcome to the Extensibility Hands-On Workshop at re>≡CAP 2023.
In this workshop, you will learn how to verticalize and customize SaaS applications using the intrinsic extensibility capabilities of the SAP Cloud Application Programming Model. We will explore feature-toggled verticalizations as a SaaS provider and demonstrate how to create and share prebuilt extension packages as SAP partners, which customers can reuse to compose tailored solutions. Additionally, we will work with an experimental feature to create custom business logic using a secure sandbox.
We will illustrate this by walking through the following use cases:
- SAP builds an incidents management app, served as a SaaS solution, subscribed by three customers: 1, 2, 3.
- Customer 1 vends solar panels and wants specific system details to be entered when opening incidents, so extend incidents objects by respective fields
- Customer 1 decides to share what they did as a pre-built verticalization package for reuse by other vendors in the solar panel industry
- SAP decides to offer that very same extension as a standard toggled feature of the incidents app, turned on or off on demand.
In summary, we'll cover all the range of extensibility features offered by CAP, as depicted in this illustration:
