Create a communication arrangement to connect your ABAP Environment to an external system - either SAP or third-party.

You will learn

  • How to create a Communication Arrangement (see below) for SAP CP Cloud Foundry Service Integration. You can then use this communication arrangement, for example to connect your ABAP Environment instance to an external API
  • How to test this arrangement by creating a specific destination pointing to an external API

Prerequisites

The communication scenario SAP_COM_0276 is predefined by SAP. It allow you to, for example, exchange data between an ABAP Environment instance and an on-premise S/4HANA System, or a third-party API.
A communication arrangement specifies the metadata for a specific communication scenario, such as your host system and the authentication method. This metadata is contained in a service key. You can then define one or more specific destinations for this arrangement.

Throughout this tutorial, objects name include the suffix 2 or XXX. Replace this suffix with your group number or initials.

Step 1: Create a Cloud Foundry destination service instance

  1. In SAP Cloud Cockpit: Navigate to your Space (such as Dev).

  4. Accept the defaults and choose Next > Next > Next.

  5. On the Confirm screen, enter an instance name EXTERNAL_API_XXX, then choose Finish.

  2. Then enter the following (replacing xxx with your group number). Then choose Save:

    • Name = Z_CHUCKNORRIS_xxx
    • URL = http://api.icndb.com/jokes/random?limitTo=[nerdy]
    • Proxy type = Internet
    • Authentication = NoAuthentication

  3. Enter the name you chose for your destination service instance in SAP Cloud Cockpit, that is EXTERNAL_API_XXX.

  4. Paste in the service key and choose Create.

Step 7: Add the service instance name

Still in the Communication Arrangement, in the Additional Properties panel, replace the default value EXTERNAL_API_XXX of the property Service Instance Name, with another value such as OutboundComm_for_RFCDemo_XXX. (To avoid confusion, make the Communication Arrangement name and the service instance name different).
