DT269 - Rethink Workflow Customization for SAP S/4HANA

DT269 - Extensibility for SAP Intelligent Trade Claims Management(ITCM) from project Kyma

This repository contains the material for the SAP TechEd 2020 session called DT269 - Extensibility for SAP Intelligent Trade Claims Management(ITCM) from the project Kyma.

Overview

This session introduces attendees to SAP ITCM extensibility from Kyma runtime, which brings smooth integration experiences between ITCM and Kyma runtime. The extensibility not only makes possible integration between ITCM and SAP on promise solution via Kyma runtime but also can be leveraged by partners to provide customized solutions and full fill their e2e user cases around ITCM.

• ITCM
  A Kubernetes based SaaS offering, behind the scenes, is composed of serval micro-services. Communication with each other is mostly events, which is known as an event-driving architecture.

• Kyma runtime

Kyma is a cloud-native extensibility framework developed to overcome the challenges of digital transformation, which include heterogeneous product portfolio, monolithic deployments, and cloud-native development. Our goal is to provide application extensions in a cloud-native fashion and with increased agility through seamless integration with the products.

ITCM build-in supports for Kyma runtime, in ITCM Extension Center, users can easily register Kyma runtime, publish Event Mesh or Open API to Kyma runtime. Use a serverless function for a customized solution in Kyma runtime. With a serverless function, partners can focus on the integration logic only. CI/CD part like building, deployment, autoscaling, etc., will be taken over by Kyma runtime.

The exercises demonstrate an e2e integration case from ITCM to Kyma step by step.
