Validate HTTP and HTTPS ports in Internet Communication Manager (ICM)

For SAP systems hosted on Google Cloud, the VM metadata is stored on a metadata server, which is only accessible through an HTTP port. HTTP port activation is required for authentication. Therefore, when your SAP system is hosted on a Compute Engine VM instance, you must ensure that an HTTP port is active to access VM metadata and enable authentication. You must also ensure that an HTTPS port is active for subsequent API calls.

If your SAP system is hosted outside Google Cloud, then activation of the HTTP port is not required.

To validate the HTTP and HTTPS ports, perform the following steps:

  1. In the SAP GUI, enter transaction code SMICM.
  2. On the menu bar, click Goto > Services. A green check in the Actv column indicates that the HTTP and HTTPS ports are active.

For information about configuring the HTTP and HTTPS ports, see HTTP(S) Settings in ICM.

Ensure outbound network egress

The SAP application server must connect to Google Cloud APIs through HTTPS.

  • For your SAP host system, confirm that the firewall rules and proxies allow HTTPS connection from servers outside the Compute Engine VM instances. For more information, see Create and start a VM instance.
  • Make sure that the access to reach the Google Cloud APIs is not restricted from a networking perspective.

Manage authorizations

To access the ABAP SDK for Google Cloud specific transactions, you need to grant users access to the SDK authorization object. The SDK transport files include the SDK authorization object ZGOOG_SDK and authorization group ZSGC.

To grant access to the SDK transactions, perform the following steps:

  1. In the SAP GUI, enter transaction code PFCG.
  2. Define a role for the SDK.
  3. For the authorization object ZGOOG_SDK, grant the role access to the authorization Activity 16.

To limit access to the SDK configuration tables, perform the following steps:

  1. In the SAP GUI, enter transaction code PFCG.
  2. Define a role for restricting access to the SDK configuration tables.
  3. To restrict the access to authorization object S_TABU_DIS, exclude the authorization group ZSGC.

Set up Google Cloud security

If your SAP system is hosted on Google Cloud, then configure the following on the host Compute Engine VM instance:

Set up authentication

To use the Google Cloud APIs, you must confirm your identity by authentication. For information about authentication options to Google Cloud and setup steps, see Authentication.

After you complete the authentication setup, you can start using the Quickstarts to create sample programs.

Configure the ABAP SDK for Google Cloud

This section explains the configurations for the ABAP SDK for Google Cloud.

Specify Google Cloud endpoint

The ABAP SDK for Google Cloud provides the following options for specifying the API endpoint when calling a Google Cloud API using the API client library class:

Default endpoints

By default, the constructor method of the API client library class contains HTTP endpoints for the supported Google Cloud APIs. The client library uses these endpoints when a method is called to perform an operation on API resources.

Use RFC destinations for endpoints

If you need to utilize any of the following features, then use RFC destinations to establish connection to Google Cloud:

  • If you use a proxy server in your SAP landscape and want to use the same to send the HTTP requests to Google Cloud.
  • If you want the SDK to access Google Cloud APIs through Private Service Connect endpoints in your VPC network.
  • If you want to use HTTP compression.
  • If you want to access region specific endpoint of an API.

The transport files of the ABAP SDK for Google Cloud contain the following sample RFC destinations for the Google Cloud API endpoints:

Sample RFC destination name Notes
GOOG_IAMCREDENTIALS This RFC destination targets the IAM API.
GOOG_OAUTH2_TOKEN This RFC destination targets Google Cloud endpoint for token based authentication.
GOOG_PUBSUB_V1 This RFC destination targets the Pub/Sub API.
GOOG_TRANSLATION_EU_V3 This RFC destination targets the Cloud Translation v3 API.

To create an RFC destination, perform the following steps:

  1. In the SAP GUI, enter transaction code SM59.

  2. Create new RFC destinations by copying the sample RFC destinations.

  3. For the RFC destinations that you created, make sure the Connection Type is set as follows: G - HTTP connection to external server.

  4. Go to the Technical Settings tab and enter the following details:

    • Target Host: enter the Google Cloud API hostname. For example, you can use translation.googleapis.com.
    • Path Prefix: enter the resource path. For example, you can use /language/translate/.

    • Service No.: enter 443. This port number used for secure communication.

      To gather the Google Cloud API specific details that you need for creating an RFC destination, see Gather details for creating an RFC destination.

  5. Go to the Logon & Security tab and make sure that the SSL Certificate field is set with the option DFAULT SSL Client (Standard).

  6. Optional: You can configure proxy settings, enable HTTP compression, and specify Private Service Connect endpoints.

  7. Save your changes.

To use RFC destinations to connect to Google Cloud APIs, you need to configure RFC destinations in the service mapping table that map RFC destinations to a client key. For more information about the service mapping table, see Table /GOOG/SERVIC_MAP.

Gather details to create an RFC destination

To get the details that you need to create an RFC destination, perform the following steps:

When you use RFC destinations to connect to Google Cloud, you can route communication from the SDK through the proxy server that you're using in your SAP landscape.

If you do not want to use a proxy server or don't have one in your SAP landscape, then you can skip this step.

To configure proxy server settings, perform the following steps:

  1. In the SAP GUI, enter transaction code SM59.

  2. Select your RFC destination that targets the required API.

  3. Go to the Technical Settings tab, and then enter values for the fields in the HTTP Proxy Options section.

You need to configure proxy server settings for each API that you plan to access using the SDK.

Enable HTTP compression

When you use RFC destinations to connect to Google Cloud, you can enable HTTP compression.

We recommend enabling HTTP compression if your SAP system is not running on Google Cloud. Before you enable HTTP compression in your production environment, test and compare the benefits based on your landscape setup, as HTTP compression might involve compression and decompression overhead. For more information from SAP, see SAP Note 1037677 - HTTP compression compresses certain documents only.

If you do not want to enable this feature, then you can skip this step.

To enable HTTP compression, perform the following steps:

  1. In the SAP GUI, enter transaction code SM59.

  2. Select your RFC destination that targets the required API.

  3. Go to the Special Options tab.

  4. For the HTTP Version field, select HTTP 1.1.

  5. For the Compression field, select an appropriate value.

Specify Private Service Connect endpoints

If you want the ABAP SDK for Google Cloud to use Private Service Connect endpoints to allow private consumption of Google Cloud APIs and IAM, then you need to create those endpoints in your Google Cloud project and specify them in the respective RFC destinations.

If you want the SDK to continue using the default, public API endpoints to connect to Google Cloud APIs and IAM, then skip this step.

To configure the SDK to use your Private Service Connect endpoints, perform the following steps:

  1. In the SAP GUI, enter transaction code SM59.

Token caching

If the SDK is used in a high call volume use case where multiple API method calls are performed in a short duration, then enable caching for the access token or API key that the client key configuration obtains to access Google Cloud APIs.

Enabling token caching makes sure that an access token or API Key is reused until it expires or is revoked, which in turn reduces the number of HTTP calls made to retrieve new access tokens or API keys.

To enable token caching, select the Token Caching flag in the client key table.

When you enable token caching, the access token is cached in the Shared Memory of the application server for the duration that is set for the Token Refresh Seconds field in the client key table. If Token Refresh Seconds is not specified or is set to 0, then the access token is cached for the value specified in the CMD_SECS_DEFLT parameter in advanced settings.

Clear the cached access token

When token caching is enabled and you update the roles assigned to the service account that the ABAP SDK for Google Cloud uses to access the relevant APIs, the new access token that corresponds to the updated roles is retrieved only after the existing cached token expires. In such situations, you can clear the access token manually.

To clear the cached access token, perform the following steps:

  1. In SAP GUI, execute the transaction code /GOOG/SDK_IMG.

    Alternatively, execute the transaction code SPRO, and then click SAP Reference IMG.

  2. Click ABAP SDK for Google Cloud > Utilities > Clear Cache.

  3. Select an option as appropriate:

        These transport files do not provide additional functionality, other than the OAuth 2.0 client credentials based authentication. For OAuth 2.0 client credentials based authentication, first import the transport files for the supported Google Cloud APIs, and then import the transport files for OAuth 2.0 client credentials.

        To use OAuth 2.0 client credentials, your SAP system must support OAuth 2.0. For information about the SAP systems that support OAuth 2.0, see SAP Note 3041322 - OAuth 2.0 Client: Downport of grant type Client Credentials.
