Connect to SAP Datasphere

As a BigQuery administrator, you can create a connection to access SAP Datasphere data. This connection enables data analysts to query data in SAP Datasphere.

Before you begin

Required roles

To get the permissions that you need to connect to SAP Datasphere, ask your administrator to grant you the BigQuery Connection Admin (roles/bigquery.connectionAdmin) IAM role on the project. For more information about granting roles, see Manage access.

You might also be able to get the required permissions through custom roles or other predefined roles.

Connect BigQuery to SAP Datasphere

You can connect BigQuery to SAP Datasphere in the Google Cloud console or the bq command-line tool.

Console

  1. In the Google Cloud console, go to the BigQuery page.

    Go to BigQuery

  2. In the Explorer panel, click add Add.

  3. In the search field, search for and select Connections to external data sources.

  4. In the External data source dialog, do the following:

    • For Connection type, select SAP HANA.
    • For Connection ID, enter a connection ID to identify this connection.
    • For Location type, specify a region of the BigQuery dataset to be combined with the data from SAP Datasphere. Queries that use this connection must be run from this region.
    • Optional: For Friendly name, enter a user-friendly name for the connection, such as My connection resource. The friendly name can be any value that helps you identify the connection resource if you need to modify it later.
    • Optional: For Description, enter a description for this connection resource.
    • For Encryption, select either Google-managed encryption key or Customer-managed encryption key (CMEK). The use of a CMEK is optional.
    • For Host:port: enter the host and port of the SAP database instance, as shown in the Database User Details in the SAP Datasphere web console, in the format HOST:PORT.
    • For Username: enter the database username from Database User Details in the SAP Datasphere web console. For example, MY_SPACE#BIGQUERY.
    • For Password: enter the database user's password.

  5. Click Create connection.

bq

Enter the bq mk command with the following flags:

  bq mk \
  --connection \
  --location=LOCATION \
  --project_id=PROJECT_ID \
  --connector_configuration '{
    "connector_id": "saphana",
    "endpoint": {
      "host_port": "HOST_PORT"
    },
    "authentication": {
      "username_password": {
        "username": "USERNAME",
        "password": {
          "plaintext": "PASSWORD"
        }
      }
    }
  }' \
  CONNECTION_ID

Replace the following:

  • LOCATION: specify a region of the BigQuery dataset to be combined with the data from SAP Datasphere. Queries that use this connection must be run from this region.
  • PROJECT_ID: enter your Google Cloud project ID.
  • HOST_PORT: enter the host and port of the SAP database instance, as shown in the Database User Details in the SAP Datasphere web console, in the format HOST:PORT.
  • USERNAME: enter the database username from Database User Details in the SAP Datasphere web console. For example, MY_SPACE#BIGQUERY.
  • PASSWORD: enter the database user's password.
  • CONNECTION_ID: enter a connection ID to identify this connection.

Share connections with users

You can grant the following roles to let users query data and manage connections:

  • roles/bigquery.connectionUser: enables users to use connections to connect with external data sources and run queries on them.

  • roles/bigquery.connectionAdmin: enables users to manage connections.

For more information about IAM roles and permissions in BigQuery, see Predefined roles and permissions.

Select one of the following options:

Console

  1. Go to the BigQuery page.

    Go to BigQuery

    Connections are listed in your project, in a group called External connections.

  2. In the Explorer pane, click your project name > External connections > connection.

  3. In the Details pane, click Share to share a connection. Then do the following:

    1. In the Connection permissions dialog, share the connection with other principals by adding or editing principals.

    2. Click Save.

bq

You cannot share a connection with the bq command-line tool. To share a connection, use the Google Cloud console or the BigQuery Connections API method to share a connection.

API

Use the projects.locations.connections.setIAM method in the BigQuery Connections REST API reference section, and supply an instance of the policy resource.
