Use Studio to Configure SAP S/4HANA SOAP Connector 2.1 - Mule 4

Anypoint Studio (Studio) editors help you design and update your Mule applications, properties, and configuration files.

To add and configure a connector in Studio:

If you are new to configuring connectors in Studio, see Use Studio to Configure a Connector.

Create a Mule Project

In Studio, create a new Mule project in which to add and configure the connector:

  1. In Studio, select File > New > Mule Project.

  2. Enter a name for your Mule project and click Finish.

Add the Connector to Your Project

Add SAP S/4HANA SOAP Connector to a Mule project to automatically populate the XML code with the connector’s namespace and schema location, as well as to add the required dependencies to the project’s pom.xml file.

  1. In Studio, create a Mule project.

  2. In the Mule Palette view, click (X) Search in Exchange.

  3. In Add Modules to Project, type SAP S/4HANA SOAP in the search field.

  4. Click the SAP S/4HANA SOAP connector name in Available modules.

  5. Click Add.

  6. Click Finish.

Adding a connector to a Mule project in Studio does not make that connector available to other projects in your Studio workspace.

Configure an Input Source

An input source initiates a flow when a specified condition is met. You can configure one of these input sources to use with SAP S/4HANA SOAP Connector:

  • Outbound Message Listener, which listens for incoming SAP S/4HANA SOAP outbound messages

  • HTTP Listener, which initiates a flow each time it receives a request on the configured host and port

  • Scheduler, which initiates a flow when a time-based condition is met

For example, to configure HTTP Listener, follow these steps:

  1. In the Mule Palette view, select HTTP > Listener.

  2. Drag Listener to the Studio canvas.

  3. On the Listener tab, optionally change the value of the Display Name field.

  4. Specify a value for the Path field.

  5. Click the plus sign (+) next to the Connector configuration field to configure a global element that can be used by all instances of HTTP Listener in the app.

  6. On the General tab, specify connection information.

  7. On the TLS tab, optionally specify TLS information.

  8. On the Advanced tab, optionally specify reconnection information, including a reconnection strategy.

  9. Click Test Connection to confirm that Mule can connect with the specific server.

  10. Click OK.

Add a Connector Operation to the Flow

When you add a connector operation to your flow, you immediately define a specific operation for that connector to perform.

To add an operation for SAP S/4HANA SOAP Connector, follow these steps:

  1. In the Mule Palette view, select SAP S4 HANA SOAP and then select the desired operation.

  2. Drag the operation onto the Studio canvas to the right of the input source.

Global Configuration Elements

To use SAP S/4HANA SOAP Connector in a Mule app, you can configure a global SAP S/4HANA configuration element for use by SAP S/4HANA Connector operations in your application.

You can put placeholder values in the mule-artifact.content configuration file in the src/main/resources folder of your project.

You can either enter your credentials in the global configuration content or reference a configuration file that contains the values for your credentials. Using a configuration file is recommended for simpler maintenance and better reuse of your project. Keeping these values in a separate file is useful if you need to deploy to different environments, such as production, development, and QA, where access credentials might differ.

Configure the SAP S/4HANA SOAP Config

When you configure a connector, it is best to configure a global element that can be used by all instances of that connector in the app. Configuring a global element requires you to provide the authentication credentials the connector uses to access the target SAP S/4HANA system. SAP S/4HANA Connector supports both Basic authentication and OAuth 2.0 client credentials authentication.

To configure the global element for SAP S/4HANA SOAP Connector, follow these steps:

  1. In your project, click the Global Elements tab at the base of the canvas.

  2. In the Global Configuration Elements screen, click Create:

    sap hana global config wizard
  3. In the Choose Global Type wizard, expand Connector Configuration, select SAP S/4HANA SOAP Config, and click OK.

  4. In the General tab, select the connection authentication from the Connection drop-down:

  5. Enter the required information for the selected connection type and click OK.

  6. Click Test Connection to ensure that your access credentials are correct.

  7. Click the Advanced tab to configure the following values:

    Studio Field Description

    Discovery Service Enabled

    Feature switch for service discovery. If disabled, the service discovery relative path is not applied.

    Discovery Service Path

    Relative path from the base URL to the service to use for automatic services discovery

    Service directory

    Common HTTP directory for all SAP services. You can leave this parameter blank and specify the HTTP directory individually for every service in the unlisted services list.

    Unlisted services

    List of services to add to the list of discovered services

    Service discovery resolution timeout

    Connection timeout for service discovery

    Service discovery timeout unit

    Time unit to use in the service discovery resolution timeout configuration

    Default headers

    Custom headers to include in each request sent

    Default query parameter

    Custom query parameters to include in each request sent

    TLS configuration

    TLS configuration

    Proxy configuration

    Configuration for executing requests through a proxy

  8. Click OK to save the global connector configuration.

Basic Authentication

Enter the following information on the General tab of the Global Element Properties screen to configure Basic authentication:

  • Service Base URL
    URL of the SAP S/4HANA instance you want to manage

  • Username
    User name used to initialize the session

  • Password
    Password used to authenticate the user

OAuth 2.0 Client Credentials Authentication

Enter the following required information on the General tab of the Global Element Properties screen to configure OAuth 2.0 client credentials authentication:

  • Service base URL
    Base URL of the service provider of the SAP S/4HANA system to access from the connector
    All other endpoints are derived from the base URL.

  • Client ID
    OAuth client ID that is registered with the service provider.

  • Client secret
    OAuth client secret that corresponds to the client ID and is registered with the service provider.

Configure the SAP S/4HANA SOAP Listener Config

Use the Global Element Properties configuration dialog to configure a global element for SAP S/4HANA SOAP Connector:

  1. In your project, click the Global Elements tab at the base of the canvas.

  2. In the Global Configuration Elements screen, click Create:

    sap hana source global config wizard
  3. In the Choose Global Type wizard, expand Connector Configuration, select SAP S/4HANA SOAP Listener Config, and click OK.

  4. Configure the following values in the General tab:

    • HTTP Listener
      Reference to a global HTTPS Listener configuration, for example: HTTPS_Listener_config. This configuration must be secured by using HTTPS protocol in order to receive outbound messages from the SAP S/4HANA system.

    • WSDL Path
      Specify the paths to the WSDL definitions to use for resolving metadata keys.

    • Encoding
      Character encoding used in the messaging.

  5. Click OK to save the global connector configuration.

It is possible to share the same path between multiple sources, but sources that share a path cannot listen to the same message type.

The list of message types specifies the message types the source can listen to. Message types are built from the provided WSDL definitions. The message type ANY, which is always present, allows the source to listen to any outbound message type sent from the SAP S/4HANA system.
