SAP Customer Checkout is a powerful point-of-sales (POS) solution. One of the strengths of the solution is the real-time integration with your ERP system for real-time stock overview, live sales updates and more.

If you are using SAPs S/4HANA Public Cloud solution with Retail functionality enabled, SAP Customer Checkout provides out-of the box integration for:

  • Article synchronisation (including pricelist updates) from S/4HANA Retail to SAP Customer Checkout

  • Customer synchronisation from S/4HANA Retail to SAP Customer Checkout

  • Live-Update of Sales and financial data from SAP Customer Checkout to S/4HANA Retail

  • Live Stock Overview in SAP Customer Checkout


This blog post describes the steps that have to be performed in SAP Customer Checkout and SAP S/4HANA  Public Cloud Retail to activate the integration.

The blog post is divided into the following steps:

  1. Prerequisites

  2. Basic Setup

  3. Inbound Services SAP Customer Checkout

  4. Outbound Services S/4HANA Public Cloud Retail

  5. Inbound Service S/4HANA Public Cloud Retail

  6. Outbound Services SAP Customer Checkout


 

Prerequisites


A few prerequisites have to be fulfilled for the integration:

Obviously an S/4HANA Public Cloud Subscription including Retail functionality is required (The integration is also possible with S/4HANA private cloud/on-premise, however this article just describes the public cloud integration)

SAP Customer Checkout Manager (SAP Customer Checkout Manager) has to be installed ideally with FP16 or above (FP14 and above are possible as well, but might be limited in functionality) and has to be reachable through internet . This can be achieved either with a cloud deployment (available from SAP Partners) or by exposing Customer Checkout Manager SOAP-API to the internet (access may be restricted e.g. to SAP Cloud IP-Ranges).

S/4HANA Public Cloud communication is only possible via SSL, i.e. SAP Customer Checkout Managers Tomcat Server has to be configured for SSL/HTTPS.

Basic Setup


Before the integration scenarios can be configured and activated a few basic steps have to be performed (Please also have a look at this blog for some more details.
