This is part 1 of the 6 series blog. This is an Introduction that explains the Use case, Solution Architecture, High-Level functionality, and context of this blog series.

 

This blog series is divided into 6 parts:

Part 1: Introduction

Part 2: SAP Ariba – API Setup

Part 3: SAP Integration Suite – Integration Flows Build

Part 4: Ariba Requisitions Service Application

Part 5: Ariba Requisitions Fiori Application

Part 6: Central Fiori Launchpad Setup


Part 1: Introduction


Use Case


Develop a simple SAP Fiori application to display SAP Ariba Requisitions data without any persistence layer and make the SAP Fiori application accessible via SAP BTP Central Fiori Launchpad

 

Solution Architecture



Picture 1


 

Architecture Components


Fiori Launchpad: This is the SAP BTP Launchpad Service. User will access the Requisitions Fiori tile on Fiori Launchpad.

Ariba Requisitions Fiori Application: SAP UI5 application built using SAP Business Application Studio

Ariba Requisitions Service: SAP CAP application built using SAP Business Application Studio

Integration Suite: Integration Flows built in SAP Integration Suite to pull Requisition data from SAP Ariba using SAP Ariba APIs.

SAP Ariba: SAP Ariba Procurement application that is hosting the Requisition data. Requisition data can be accessed via the SAP Ariba APIs.

 

High-Level Functional Flow



  1. User accesses BTP Central Fiori Launchpad

  2. User clicks on the Requisitions Fiori tile on BTP Central Fiori Launchpad.

  3. Requisitions Fiori tile directs the request to the Ariba Requisitions Fiori application deployed in BTP.

  4. Ariba Requisitions Fiori application triggers Ariba Requisitions Service deployed in BTP.

  5. Ariba Requisitions Service pulls Requisitions data from SAP Ariba via SAP Ariba APIs. Any complex programming logic can be implemented here.

  6. Ariba Requisitions Service transforms the Requisition data into the required format and provides it to the Ariba Requisitions Fiori application. Any complex programming logic can be implemented here.

  7. SAP Ariba Requisition data is displayed to the User.
