Establishing Connectivity Between SAP S/4HANA Cloud and SAP BTP

Objective

After completing this lesson, you will be able to Learn about the connectivity concepts between SAP S/4HANA Cloud and SAP BTP.

Connectivity Concepts Between SAP S/4HANA Cloud and SAP BTP

Introduction

You want to establish connectivity between your SAP S/4 HANA Cloud system and a SAP BTP subaccount. To allow inbound communication with the SAP S/4HANA tenant, you must explicitly permit the APIs to be accessible from external systems such as SAP BTP. SAP S/4HANA system only allows APIs that you choose to expose to the cloud.

In this learning journey, we use the SAML Assertion Authentication method to access the SAP S/4HANA Cloud APIs with principal propagation. However, not all SAP S/4HANA Cloud APIs support oAuth. For those that do not support it, you must set up communication with basic authentication.

Details of Connectivity Concepts Between SAP S/4HANA Cloud and SAP BTP

The communication management in SAP S/4HANA Cloud consists of the following functionalities:

Communication arrangement
A communication arrangement describes a communication scenario with a remote system during configuration time. It provides the necessary metadata for service configuration.
Communication system
A communication system represents the communication partner with all technical information that is required for communication, for example, hostname, identity, user information, and certificates.
Communication user
A communication user is a special type of technical user that is assigned to a communication system. You create a communication user for particular communication scenarios.
Communication scenario
A communication scenario defines the communication between external systems and your own SAP cloud system. It bundles inbound and outbound services and additional properties that are required for configuration settings.

You can choose between three different concepts for creating a connection between SAP S/4HANA Cloud and the SAP BTP subaccount:

  • SAML Assertion Authentication
  • Basic Authentication
  • Client Certificate Authentication

Set Up Communication Systems and Arrangements in SAP S/4HANA Cloud

Business Scenario

To allow inbound communication with the SAP S/4HANA tenant, you need to explicitly allow the APIs to be accessible from external systems like SAP BTP.

In this learning journey, we use the SAMLAssertion Authentication method to access the SAP S/4HANA Cloud APIs with principal propagation. As not all SAP S/4HANA APIs support oAuth, you need to set up a communication for the Product Master Data Including Classification API with basic authentication.

Task Flow

In this exercise, you perform the following tasks:

  1. Create a communication system for SAMLAssertion with your SAP BTP subaccount.
  2. Create a communication system and arrangement for basic authentication.

Prerequisites

  • You have successfully completed the exercise: Build a Custom Business Object in SAP S/4HANA Cloud.
  • In SAP S/4HANA Cloud, your user has the Business Catalog for Communication Management SAP_CORE_BC_COM.
  • In the SAP BTP subaccount, your user owns the Destination Administrator role collection.

Task 2: Create a Communication System and Arrangement for Basic Authentication

Steps

  1. Create a communication system in SAP S/4HANA Cloud.

    Currently, not all SAP S/4HANA APIs support SAMLAssertion. For those APIs, you must set up a communication system with basic authentication. For our scenario, we use the Product Master Data Including Classification API that does not support oAuth. This API is read-only and in our application you call it with parameters. So, users do not access any data, because they are not permitted to access data.

    1. Log on to your SAP S/4HANA Cloud System.

    2. Search for and open the Communication Systems application.

    3. Choose New.

    4. Set a unique System ID and System Name.

    5. Choose Create.

  2. Define the communication system and create a communication user.

    FieldValue
    Logical SystemS4C
    Business SystemS4C
    Inbound Onlychecked

    1. In the Technical Data part, set a Logical System and a Business System ID.

    2. Check the Inbound Only box.

    3. Add a user for Inbound Communication.

    4. In the New Inbound Communication User dialog box, select New User.

    5. At the Create Communication User pane, set the User Name and Description.

    6. Choose Propose a Password.

    7. Copy it to a secret store. You need it in the next exercise.

    8. Choose Create to save the Communication User.

    9. In the dialog box, choose OK to add it to the Communication System.

    10. Save the Communication System.

  3. Create a communication arrangement for the Product Classification API.

    1. Open the Communication Arrangements application and select New.

    2. Select the SAP_COM_0309 scenario and add an arrangement name.

    3. Choose Create.

    4. In the Communication Arrangement panel, select the Communication System that you created in the last section.

      Result

      The Communication User adds automatically.

    5. Copy the Service URL. You need it in the next exercise.

    6. Select Save.

  4. If there are issues, test all APIs with basic authentication.

    If you face problems in your test environment with SAMLAssertion, you can also test all APIs with basic authentication. Create additional communication arrangements as in the previous step, with the following scenario IDs:

    FieldValue
    Purchase OrderSAP_COM_0053
    DefectSAP_COM_0153
    Custom Business Object for GR ChecksYY1_GRCHECK
    Custom Business Object for ChecklistsYY1_CHECKLIST

    Result

    You created the communication systems to expose the relevant data for our scenario. In the next exercise, we set up the communication part on the SAP BTP side.

Result

You created all the destinations required to send data across SAP BTP and SAP S/4HANA Cloud.

SAML Assertion Authentication and OAuth SAML Bearer Assertion Authentication

SAML Assertions are messages exchanged between two providers: an identity provider and a service provider that confidentially identifies a user.

SAP Business Technology Platform supports applications to use the SAML bearer assertion flow for consuming OAuth-protected resources. Applications need not be created to handle some of OAuth's complexities. They can reuse existing identity providers for user data. Users are authenticated by using SAML against the configured trusted identity providers. You use the SAML assertion to request an access token from an OAuth authorization server. This access token is injected automatically in all HTTP requests to the OAuth-protected resources.

Before you can authenticate to an SAP S/4HANA Cloud system using SAML2 Bearer assertions, transmitted through the authorization header, you must configure a trusted relationship to the required SAML Identity Provider (token issuer). In our case, the SAP BTP subaccount acts as a token issuer. The trust is done through certificate import. For the configuration, use the Communication System application.

In SAP BTP, you can retrieve a generated SAML Assertion from the Destination service by using the SAMLAssertion authentication type. In contrast, OAuth SAML Bearer Assertion Authentication sends the generated SAML assertion to an OAuth server to get a token. In our scenario, this is the SAP S/4HANA Cloud system. The destination service provides functionality for caching the generated SAML assertion for later use and caching by the app whenever needed. This helps simplifying application development. For the user identification, the SAML assertion uses by default the NameIdentifierFormat eMail Address.

By using SAML Assertion, an authentified user can access all SAP S/4HANA Cloud APIs that support oAuth and the user has the authorization for it.

Basic Authentication

Not all SAP S/4HANA Cloud APIs support OAuth. For those that do not, you can use basic authentication. Ensure that you handle the APIs calls with parameters properly in your application, so that the user only accesses data permitted to them.

Here are the general setup steps:

  1. In the SAP S/4HANA Cloud system, use the Communication User application to create a user for basic authentication.
  2. Create a Communication System using the created user as inbound user.
  3. For each API you want to use with basic authentication, create a Communication Arrangement assigned with the defined communication system.
  4. In SAP BTP, create a Destination with the type basic authentication, using the API URL from the communication arrangement and the communication user credentials.

Client Certificate Authentication

To do this, you need a client certificate signed by a trusted certificate authority (CA). When you create a communication user in the SAP S/4HANA Cloud system, you upload the public key and add the relevant keystore to the HTTP destination in the SAP BTP cockpit.

In SAP BTP, you configure the HTTP destination by using client certificate authentication. To check the setup from end to end, you can use the app router and Java sample apps.

Summary

In this lesson, you learned the importance and concepts of connectivity between SAP S/4HANA cloud and SAP BTP subaccount.
