# Welcome to the SAP CAP & Amazon Simple Notification Service Integration App
[![REUSE status](https://api.reuse.software/badge/github.com/SAP-samples/cloud-cap-amazon-sns-integration)](https://api.reuse.software/info/github.com/SAP-samples/cloud-cap-amazon-sns-integration)

## Description
This is an example project showcases how to integrate SAP Cloud Application Programming Model (CAP) with Amazone Simple Notification Service (SNS), to build a S/4HANA business process extension project, and send out email notification if it is necessary by using Amazon Simple Notification Service.

This project showcases:

- Develop S/4HANA business process extension App by using [SAP Cloud Application Programming Model(CAP)](https://cap.cloud.sap/docs/) and [Fiori Element UI](https://ui5.sap.com/#/topic/03265b0408e2432c9571d6b3feb6b1fd)
- Consume S/4HANA On-Premise System Event by using [SAP Event Mesh](https://help.sap.com/viewer/bf82e6b26456494cbdd197057c09979f/Cloud/en-US/df532e8735eb4322b00bfc7e42f84e8d.html)
- Consume S/4AHANA On-Premise System OData API From SAP Business Technology Platform (Cloud Env)
- Send Out Email Notification by leveraging [Amazon Simple Notification Service (SNS)](https://docs.aws.amazon.com/sns/latest/dg/welcome.html)

## Business Scenario
There is a third-party firm/team responsible for validating all newly created or changed business partners data in S/4HANA system for a company. This third-party firm/team will do the validation through a standalone S/4HANA business process extension App deployed on SAP BTP platform, instead of getting access into the S/4HANA system.

In this standalone extension App, the validator could review the business partner's data, perform updates on the business partner address if necessary, and mark business partner’s validation status as NEW, IN PROCESS, VALID, and INVALID based on the condition. The validators could receive notifications through email whenever there is a business partner's data that needs to be validated. Once the business partner data are verified, the business partner get activated in the S/4HANA System.

- The Business Partner Validation application developed using SAP Cloud Application Programming Model (Java), and deployed on the SAP Business Technology Platform.
- S/4HANA On-Premise System Sends Message to SAP Event Mesh through Enterprise Messaging Mechanism on Every Business Partner Create/Change Event
- Business Partner Validation Application Consumes Message From SAP Event Mesh Message Queue, Persists Business Partner Data Into HANA Cloud DataBase
- Business Partner Validation Application Sends Out Emial Notification to Validator Through Amazon Simple Notification Service
- Authorized Validtor Log Into Business Partner Validation Application Through Fiori Element UI
- Authorized Validtor Review/Update Business Partner Address Data, and Update Business Partner Verfication Code In Fiori Element UI
- Business Partner Validation application Consume S/4HANA On-Premise Business Partner(A2X) OData API To Update/Release Business Partner through SAP Connectivity Service and Cloud Connector.
