Prerequisites - SAP S/4HANA

Before creating and using a Connector, please review the following requirements and prerequisites.

• Configure the communication management for the required service
• Specialized Licensing Required
• Technical Assumption

Configure the communication management for the required service

The communication management apps allow you to integrate your system or solution with other systems to enable data exchange.

The communication management apps allow you to establish secure communication between your solution and other systems. The best practice to organize efficient data exchange is to proceed as follows:

• Create a Communication User
• Create a Communication System
• Create a Communications Arrangement

Create Communication User

1. Create a communication user for inbound communication according to your needs using the Maintain Communication Users app. Communication users are used by solutions to authenticate themselves to be able to post data.
2. From the initial screen, select New.

   

3. Enter a valid user name and description. SAP S/4HANA Cloud supports both Basic authentication and Client Certificate authentication. Either provide a password (basic authentication) or upload certificates for certificate-based authentication based on the requirement.
4. Select Create to save the user.

   

   You can now assign the created user to a communication system. Use the Communication Systems app for this purpose. See below.

Create Communication System

1. Create a communication system using the Communication Systems app that represents the system you want to communicate with. 
2. From the initial screen of the Communications Systems app, click New.
3. From the new Communication System dialog, define the ID and name of the new system.

   

4. Complete the required settings under the following sections:
   • General Data: Enter system ID and system name
   • Technical Data: 
   • For Inbound Only: If you want your communication system to be used for a communication arrangement based on a communication scenario that only contains inbound services, we recommend that you select the Inbound Only checkbox. If this checkbox is selected, the input fields that are only required for outbound communication disappear.

     

   • Assign communication user: To assign the communication user to the communication system for inbound communication, click on ‘+’ symbol and select the required communication user.
5. Save your changes.

   You can now establish a communication arrangement with the created system.

Create Communication Arrangement

1. Create a communication arrangement using the Communication Arrangements app. Open the Communication Arrangements app from the SAP Fiori Launchpad. Existing communication arrangements will be listed on the initial screen.
2. Select New. In the new Communication Arrangement window, select a communication scenario and define the arrangement name and then select Create. ( The communication scenario ID for the required service can be identified from the attributes tab in the SAP API Hub).
3. The new Communication Arrangements screen is now open. In the Communication System field under Common Data, select a communication system that you want your system to connect to.
4. If the communication scenario provides inbound services, you have to select the desired communication user and authentication method from the assigned communication system. The defined communication user then has the authorization to call these services.
5. Save the arrangement.
